Why Traditional Leak Detection Fails for Ethanol — And What Actually Works

Most fuel leak sensors were built with gasoline in mind. But ethanol plays by entirely different rules. Here's why that matters, and how a purpose-built detection system finally closes the gap.

If you manage fuel storage or transfer operations, you already understand the importance of leak detection. You have systems in place. You have sensors in your sumps. You run regular checks. So it might come as a surprise to learn that when it comes to ethanol specifically, most of those systems are essentially flying blind.

That's not a knock on your operations — it's a chemistry problem. Ethanol behaves in a fundamentally different way than the fuels traditional sensors were designed to catch. Understanding that difference is the first step toward actually fixing it.

The Chemistry Problem Nobody Talks About Enough

Traditional fuel leak detectors work on a simple principle: hydrocarbons float on water. When gasoline or diesel leaks into a sump or containment area, it sits on top of any water present. Sensors designed to detect a hydrophobic layer on a water surface work well for exactly that scenario.

Ethanol, however, is miscible with water. That's a fancy way of saying it mixes completely and doesn't separate. When ethanol leaks, it doesn't pool on the surface — it dissolves right in. For a sensor looking for a floating hydrocarbon layer, there's nothing to detect. The leak goes unnoticed while the contaminated water continues to spread.

"When ethanol leaks, it doesn't pool on the surface — it dissolves right in. For a sensor looking for a floating hydrocarbon layer, there's nothing to detect."

This creates a compounding problem underground. Ethanol's water solubility means contamination can migrate farther and faster through soil and groundwater than a conventional gasoline spill would. By the time the issue is discovered through traditional monitoring methods, the affected area can be significantly larger than it would have been otherwise.

Why Ethanol Is Everywhere Now — And Why That Raises the Stakes

This issue has become much more urgent in recent years because ethanol is no longer a niche product. Government blending mandates have pushed ethanol into the mainstream fuel supply at scale. Today, virtually every gallon of gasoline sold in the United States contains a meaningful percentage of ethanol, typically around ten percent, with higher blends increasingly common in certain markets.

That means refineries, blending terminals, pipeline systems, and fuel storage facilities are all handling ethanol in volumes they simply weren't a decade ago. The infrastructure wasn't always built with this in mind, and neither were the monitoring systems installed alongside it.

Regulators have taken notice. Environmental agencies treat ethanol leaks seriously, in part because of the groundwater migration risk described above. A leak that might once have been contained and remediated relatively quickly can turn into a protracted, expensive environmental response when ethanol is involved. The reputational and financial consequences of a missed detection event are real.

Where Leaks Actually Happen

Ethanol moves through a long chain before it reaches a consumer's fuel tank. It's produced, transported by rail or truck, received at blending terminals, stored in bulk tanks, measured and blended, then transferred into distribution pipelines and tanker trucks. Each one of those handoffs — every pump, fitting, valve, pipe joint, and tank seal in that chain — is a potential leak point.

The challenge isn't just detection at any one facility. It's consistent, reliable monitoring across every node of a complex distribution network, in environments ranging from climate-controlled blending rooms to outdoor storage areas exposed to rain, temperature swings, and condensation. Any detection system has to work reliably across all of those conditions without generating constant false alarms that erode operator trust.

The Naftosense Approach: Built for Ethanol, Not Adapted for It

The Naftosense FLD system was engineered from the ground up for this specific challenge. Rather than retrofitting a hydrocarbon sensor with additional capabilities, the technology is designed to detect alcohols and polar solvents as its primary function — with sensitivity to fossil fuels and hydrocarbons as a secondary benefit.

The system is configured to reliably detect ethanol at concentrations of 20 percent by volume in water. That threshold matters because regulators generally treat concentrations at or above that level as a reportable concern. Below 20 percent, ethanol contamination is typically not considered a regulatory event. The Naftosense system is tuned to the exact threshold that matters for compliance, so operators get actionable information rather than noise.

The Three Core Components

Sensing

FLD-PSP Probe

A fully encapsulated, high-performance sensing probe installed directly in sumps, containment areas, and low points. Factory-installed in a stainless steel slotted tube for protection and consistent positioning.

Acquisition

FLD-MXM-PS Module

The field-level acquisition module that interprets probe signals with intelligent thresholding. Built-in algorithms track electrical conductivity between sensor wires to minimize false positives from condensation, dust, and conductive dirt.

Control

FLD-SMP Controller

The master control module connecting the field system to facility infrastructure. Supports Modbus RTU and 4–20 mA outputs for direct integration with SCADA and PLC systems. Covers wired layouts up to one mile.

Detection Speed: What the Numbers Look Like

One question operators always ask is how fast a detection system responds once a leak occurs. The answer varies depending on what's leaking and the ambient conditions, but the Naftosense FLD-PSP probe delivers response times that are practically useful for real-world operations.

Substance	Typical Detection Time
20%–100% alcohol in water	2 to 2.5 minutes
Gasoline and other hydrocarbons	30 seconds to 10 minutes
Hydrocarbon vapors	3 to 4 minutes

A detection time of two to two and a half minutes for alcohol in water means operators can respond before a small leak becomes a large one — and well before regulators become involved.

The False Positive Problem (And Why It's Solved Here)

Here's a situation any operator with field experience will recognize: you install a sensitive detection system, and then you spend the next six months responding to nuisance alarms triggered by condensation, morning dew, cleaning water, or conductive dust settling on sensor surfaces. Eventually, operators start ignoring alarms. At that point, the detection system is worse than useless — it creates a false sense of security while providing no real protection.

The FLD-MXM-PS module addresses this directly with what Naftosense calls intelligent thresholding. The module continuously monitors electrical conductivity between sensor wires and uses a built-in algorithm to distinguish between the conductivity signature of a genuine ethanol or solvent leak and the conductivity patterns associated with environmental factors like condensation and dust. Alarm thresholds are adjustable from the monitoring panel, allowing facilities to tune sensitivity to their specific operating environment.

The result is a system that operators can trust. When an alarm triggers, it means something real has happened. That's the foundation of effective environmental compliance — not just detection capability, but detection reliability.

Integration With Existing Infrastructure

One practical concern for any new monitoring system is how it fits into existing facility infrastructure. Most industrial facilities already have SCADA or PLC systems managing a wide range of operational parameters. Adding a new monitoring technology only makes sense if it can report into those existing systems cleanly, without requiring parallel infrastructure or manual data transfer.

The Naftosense FLD system supports both Modbus RTU and 4–20 mA output interfaces, which are the two most common communication standards in industrial control environments. That means alarm data flows directly into whatever monitoring platform the facility already uses. Latching alarms with push button reset give operators clear, unambiguous status information, and alarms can also be reset remotely through a Modbus command when that's more practical. Zener barriers enable safe installation in C1D1 classified locations where many ethanol handling operations take place.

A 10-Year Warranty Worth Noting

Industrial sensors installed in harsh environments face real durability demands. The FLD system comes with a ten-year warranty — a meaningful commitment for equipment that may be buried in sumps or installed in containment pits and expected to perform reliably for years without active maintenance.

The Bottom Line

Ethanol isn't going away. If anything, its role in the fuel supply is growing. For operators handling ethanol at any point in the production and distribution chain, the question isn't whether ethanol-specific leak detection matters — it's whether your current system is actually capable of providing it.

If your detection infrastructure was installed primarily with hydrocarbon fuels in mind, there's a meaningful gap in your environmental monitoring coverage. The Naftosense FLD system was built to close exactly that gap, with technology that treats ethanol detection as a first-class problem rather than an afterthought.

Executive Summary: Getting Ahead of Leaks & Spills — Naftosense White Paper

Get the full "Getting Ahead of Leaks & Spills" white paper here.

Leaks in pipelines, storage tanks, and industrial systems present significant operational, environmental, and financial risks. Traditional detection methods — visual inspections, pressure monitoring, and infrared sensing — often fall short in terms of accuracy, speed, and cost-effectiveness. This white paper, authored by Naftosense R&D coordinator Stefan Balatchev, presents polymer absorption sensors as a modern, real-time alternative capable of detecting hydrocarbons and other chemicals with high sensitivity across a wide range of industrial applications.

Technology Overview

Polymer absorption sensors operate through three core mechanisms: selective polymer materials with high chemical affinity, physical absorption that causes measurable changes in the polymer (e.g., expansion, viscosity, dielectric properties), and signal conversion via optical, electrical, or mechanical means — most commonly via changes in electrical resistance or capacitance.

Key Applications

The technology is applicable across a broad industrial landscape, including oil and gas pipelines (particularly at block valves and pig launchers), above-ground and underground storage tanks, offshore platforms and subsea pipelines, and refineries and chemical processing plants. Notably, the sensors also support emerging energy sectors, detecting leaks of ethanol, methanol, biodiesel, sustainable aviation fuel (SAF), and liquid organic hydrogen carriers (LOHC) — positioning Naftosense as relevant to the energy transition, not just legacy fossil fuel infrastructure.

System Integration

Naftosense hardware pairs with the Lindsay SentraLink LD platform to deliver a comprehensive monitoring solution. This combination provides 24/7 web-based dashboard visibility, remote accessibility via cellular or satellite communication, battery-powered off-grid operation, and automated email/text alerts. The integrated system is designed for deployment in pipelines, tank farms, refineries, and produced water sites.

Core Value Proposition

The system can detect leaks as small as 1 ounce of product, enabling rapid response before minor incidents escalate into major environmental or operational events. Its durability, low maintenance requirements, and adaptability to harsh environments — including deep-sea conditions — make it a compelling solution for both conventional and challenging deployment scenarios.

Conclusion

Naftosense's polymer absorption sensors, combined with complementary monitoring platforms like Lindsay SentraLink LD, offer a reliable, scalable, and forward-looking approach to leak detection. The solution addresses growing regulatory pressure, aging infrastructure, and the evolving demands of new fuel technologies, making it a strong candidate for organizations seeking to proactively protect their infrastructure and minimize environmental liability.

FM7745-Approved Leak Detection: Naftosense's Approach to Loss Prevention

FM Global stands apart among commercial insurers because it focuses on preventing losses rather than simply paying claims. Through its testing and certification arm, FM Approvals, the organization defines performance standards that help facility owners detect risk earlier, limit damage, and keep critical operations running. One of the most important of these standards is FM7745, a performance-based standard that addresses leakage of water and hydrocarbons inside buildings. The intent is straightforward but powerful: identify leaks quickly, communicate that information to building management systems, and, when appropriate, trigger automatic responses that stop the release before it escalates into fire, environmental damage, or extended downtime.

FM7745 applies across an unusually wide range of industries because hydrocarbons and water are present in so many mission-critical systems. Hospitals depend on emergency generators, day tanks, fuel conditioning skids, and extensive piping networks that often run above ceilings or below floors. Data centers rely on large backup power systems with stored diesel fuel, transfer pumps, and distribution piping that must operate flawlessly under emergency conditions. Commercial buildings and manufacturing facilities introduce additional exposure through boilers, fuel-fired equipment, bulk storage vessels, underground piping, and mechanical rooms with dense concentrations of utilities. FM7745 is designed to verify that leak detection systems used in these environments perform reliably under real-world conditions, including sensitivity to small leaks, resistance to false alarms, and compatibility with automated controls.

Meeting FM7745 requirements means more than simply sensing the presence of liquid. Approved systems must demonstrate repeatable detection of both water and refined hydrocarbons, predictable response times, and stable operation when integrated into supervisory control or building automation platforms. The standard places emphasis on early warning rather than catastrophic failure, because FM Global recognizes that a slow, undetected leak often causes more damage over time than a dramatic single event. Early detection allows facility teams to correct issues while systems remain operational and before fuel vapors, corrosion, or environmental contamination create secondary hazards.

This is the operating philosophy behind Naftosense, a company that originated in demanding oil and gas environments where leaks rarely announce themselves loudly and conditions are rarely forgiving. Drawing on that background, Naftosense engineered an FM7745-approved leak detection system specifically for FM Global-insured facilities that need precision without compromise. The system scales smoothly from a single sensing point protecting a day tank or generator enclosure to expansive, distributed networks that run through long pipe corridors, containment zones, and equipment rooms. Throughout that scaling process, the design maintains the same priorities that governed its industrial roots: rapid response, mechanical durability, and consistent accuracy.

At the heart of the Naftosense system is a rope-style sensing element that behaves very differently from point sensors or float-based probes. Instead of waiting for liquid to pool at a single location, the rope sensor monitors extended linear paths where leaks are most likely to occur. When refined fuel contacts the sensing element, the system registers the change almost immediately. In controlled testing and real installations, it can detect extremely small volumes of refined hydrocarbons in under 30 seconds. That response time matters, because even modest diesel or fuel oil leaks can spread invisibly along floors, cable trays, or pipe racks before anyone notices an odor or visible sheen.

Accuracy alone does not satisfy FM7745 requirements if it comes at the cost of operational nuisance, and this is where system design becomes critical. Naftosense sensors are engineered to resist false alarms caused by humidity, condensation, cleaning solutions, or transient environmental changes. The sensing element focuses on the chemical signature of refined fuels rather than general conductivity or moisture, which allows facilities to run the system continuously without constant recalibration or alarm fatigue. That stability is essential in healthcare, data center, and manufacturing settings where alarms trigger formal response procedures.

Integration with building management and control systems further strengthens the value of an FM7745-approved solution. When the Naftosense controller detects a leak, it can immediately report the event to a central monitoring platform, providing clear location data that guides maintenance teams directly to the source. In configurations that include actuated valves, the system can also initiate rapid isolation of the affected section, limiting the amount of fuel released and reducing cleanup costs. This coordinated response aligns closely with FM Global’s loss prevention model, which favors fast, automated intervention backed by human oversight.

Long-term reliability also plays a role in risk management and return on investment. Naftosense uses cleanable, reusable rope sensors that return to service after remediation rather than requiring disposal and replacement. That approach reduces lifecycle costs and avoids the gaps in protection that often occur when consumable sensors are temporarily out of stock or overlooked during maintenance. A 10-year factory warranty across the entire leak detection system reinforces confidence that the equipment will perform as intended over the long operating life expected in insured facilities.

For facility owners and risk managers, the practical benefits of an FM7745-approved Naftosense installation are easy to quantify. Faster leak detection reduces secondary damage to structures, electrical systems, and finished spaces. Early intervention minimizes environmental exposure and fire risk associated with flammable fuels. Clear communication with building systems supports documented compliance and simplifies inspections. Over time, these outcomes help FM Global-insured clients demonstrate strong loss prevention practices, protect their staff and occupants, and potentially reduce insurance premiums tied to verified risk reduction.

In an era when facilities are expected to operate continuously and safely under increasing scrutiny, FM7745 sets a meaningful benchmark for leak detection performance. Naftosense meets that benchmark with a system built on industrial experience, engineered sensitivity, and practical durability, delivering early warning where it matters most and turning leak detection from a reactive safeguard into an active component of facility resilience.

Remote Pipeline Leak Detection: How Naftosense and Lindsay SentraLink LD Deliver Reliable Monitoring Anywhere

Pipeline operators face one of the most demanding environmental and operational challenges in modern industry—detecting leaks quickly and accurately in remote locations. Protecting natural ecosystems, maintaining regulatory compliance, and avoiding catastrophic losses all depend on early leak detection. Yet, traditional monitoring methods have long struggled to meet this challenge. Naftosense, a leader in hydrocarbon detection technology, has partnered with Lindsay Corporation to create a robust, self-sufficient solution that finally makes reliable remote leak detection practical and affordable.

For decades, operators have relied on “walk over” or “fly over” visual inspections to find leaks in remote areas. These surveys typically look for secondary evidence such as brown vegetation, oil sheens, or visible soil discoloration. While simple in concept, these methods are slow, costly, and often come too late to prevent environmental damage. A small leak may go unnoticed for weeks or months, allowing hydrocarbons to migrate underground or into waterways before discovery. Many pipeline sites—particularly at block valves, pig launchers, stub ups, and unmanned facilities—are situated far from roads or electrical power, making frequent inspection nearly impossible. Even when leaks are eventually detected, cleanup and regulatory fines can dwarf the cost of proactive monitoring.

The industry has sought alternatives for years, but remote locations pose unique technical barriers. Many monitoring systems require grid power or fiber connections to operate, limiting their usefulness in isolated environments. Others depend on SCADA infrastructure, which can be prohibitively expensive to extend to each remote site. Extreme temperature swings, humidity, and explosive atmospheres further complicate equipment deployment. Until recently, operators were forced to choose between expensive monitoring projects and the environmental risks of infrequent inspections.

Naftosense developed its Poly-Absorptive Sensor (PAS) technology to address the heart of this problem. Each PAS device detects hydrocarbon contamination through a unique absorption process that responds to even minute quantities of liquid hydrocarbons. The polymer material within the sensor absorbs hydrocarbons and triggers a measurable change, providing an early warning well before visible contamination appears. Unlike electronic gas sensors that require power-hungry heating elements, Naftosense’s design is inherently low-power and maintenance-free. The sensors are rugged, durable, and capable of continuous operation in demanding outdoor environments, making them ideal for long-term field deployment.

To enable these sensors to function in truly remote areas, Naftosense partnered with Lindsay Corporation, the manufacturer of the SentraLink LD remote monitoring system. The SentraLink LD acts as both a power source and a communications gateway for Naftosense PAS sensors, eliminating the need for external power or network infrastructure. Using primary lithium thionyl chloride batteries, each monitoring unit can operate continuously for up to three years. This extended battery life allows operators to install systems at distant block valves, uncrewed stations, and environmentally sensitive areas without ever running power lines or generators.

SentraLink LD communicates sensor data over low-cost cellular networks and, where cellular coverage is unavailable, can connect via satellite links. This capability ensures real-time visibility of pipeline conditions across vast distances. The system integrates seamlessly with the Elecsys Connect web portal, a secure, cloud-based interface that provides operators with 24/7 access to all connected sensors. Through any web-enabled device, users can view sensor status, GPS coordinates, and leak alerts overlaid on a Google Maps interface. When a leak is detected, the system instantly transmits text and email notifications that include precise location data and estimated leak volume, enabling immediate response without waiting for the next inspection cycle.

This intelligent reporting framework reduces data noise and bandwidth use by operating on a “report by exception” basis—sending updates only when a change occurs. Operators can remotely configure alarm thresholds and reporting intervals through the web portal, tailoring the system’s responsiveness to site conditions. The entire unit is housed in a NEMA 4X-rated polycarbonate enclosure for weather resistance and compliance with hazardous-area requirements. With an operational temperature range from -30°C to +70°C and tolerance for humidity up to 95%, the system remains reliable in both arctic and desert environments.

By combining Naftosense’s passive hydrocarbon detection with Lindsay’s autonomous, connected platform, operators gain a continuous, self-sustaining leak monitoring network that requires minimal maintenance. Eliminating external power and SCADA connections provides a significant cost advantage. Traditional monitoring projects can require trenching, conduit, and control wiring, which can run into tens of thousands of dollars per mile. In contrast, the Naftosense–Lindsay solution can be installed with a simple mounting process and pre-coded connectors, bringing each site online in hours rather than days.

Beyond economic efficiency, the environmental benefits are profound. Early leak detection reduces hydrocarbon release volumes, shortens cleanup times, and minimizes ecological impact. Regulators increasingly demand continuous monitoring for environmental compliance, and systems like SentraLink LD with PAS sensors meet these expectations while keeping operational costs low. For operators managing hundreds of miles of pipeline, automated detection transforms leak monitoring from a reactive obligation into a proactive asset protection strategy.

The system’s adoption by major oil and gas companies underscores its credibility in real-world use. Operators have deployed it at hundreds of remote sites to monitor valves, junctions, and containment areas that once relied solely on manual inspection. In these installations, the combination of Naftosense sensors and SentraLink LD units has demonstrated consistent reliability and rapid leak detection even under the most challenging field conditions.

As pipeline networks expand and environmental regulations tighten, the industry can no longer afford to rely on slow, manual inspection methods. The integration of Naftosense Poly-Absorptive Sensors with Lindsay’s SentraLink LD monitoring system provides a proven, cost-effective way to monitor remote assets and respond instantly to potential leaks continuously. By making high-performance leak detection possible anywhere, this partnership sets a new standard for environmental stewardship and operational efficiency in the pipeline industry.

Naftosense Launches New Ethanol Leak Detection System

Why Ethanol Leak Detection Matters

Ethanol plays an increasingly important role in modern fuel blends. Oil and gas companies now produce, transport, and store ethanol on a massive scale as they meet government blending mandates and consumer demand for lower-emission gasoline. Unlike traditional hydrocarbons, ethanol mixes easily with water. That simple fact creates a problem. Leaks often escape traditional detection systems because the alcohol dissolves into water rather than separating on the surface like gasoline or diesel.

This challenge presents ethanol handling as a distinct kind of risk. Contaminated groundwater can spread fuel compounds farther and faster when ethanol is present. Regulators take a closer look at these leaks because they can create long-lasting environmental and safety issues. Companies need a reliable way to identify problems before they turn into violations or costly cleanups.

The Role of Ethanol in Fuel Blending

Ethanol provides clear benefits as a fuel additive. It increases octane ratings and helps gasoline burn more completely, reducing some types of tailpipe emissions. It is also widely available, with the United States producing billions of gallons each year, mostly from corn. Oil companies blend it into gasoline at levels ranging from 10 to 15 percent for everyday use, and sometimes higher for specialized applications.

Despite these benefits, ethanol brings new challenges. Higher blends reduce fuel economy and can place stress on engines not designed for them. Production plants release significant amounts of hazardous air pollutants, and large-scale cultivation of corn raises concerns about land use and greenhouse gas emissions. These debates underscore the industry's need to continually improve its environmental performance at every stage, from plant operations to storage tanks.

How Leaks Happen in Transfer and Storage

Ethanol moves from plants to terminals and ultimately into pipelines and trucks. Each step creates opportunities for leaks. Unlike crude oil or refined fuels, ethanol does not stay separate from water. When a tank, pipe, or fitting leaks, the ethanol can dilute into surrounding water sources. Once this happens, most conventional sensors fail to detect the problem because they are designed to spot hydrocarbons floating on water, not alcohol dissolved within it.

That limitation creates blind spots for operators. Undetected leaks can damage aquifers, violate environmental laws, and spark expensive remediation projects. Companies need technology that can distinguish ethanol even when it is diluted in water.

The Naftosense Solution

Naftosense developed a new detection system built specifically for this challenge. The technology ignores the presence of water and zeroes in on ethanol and other alcohols. It works even at 20 percent concentration, which is the level regulators see as a real problem, while anything under 20 percent usually isn’t treated as a threat. This approach gives operators confidence that they can identify issues promptly and take action before minor problems escalate into significant events.

Oil and gas companies now have a tool designed for the realities of ethanol blending. By addressing the weaknesses of conventional leak detection, Naftosense offers a practical solution that supports both regulatory compliance and corporate sustainability goals. Companies that invest in this system can strengthen their safety programs, protect the environment, and build public trust at a time when every gallon of biofuel faces scrutiny.

Looking Ahead

Ethanol will remain a cornerstone of gasoline production for the foreseeable future. As production expands, so do the risks of leaks during transfer, storage, and handling. The companies that succeed in this new era will be those that not only meet blending mandates but also show they can manage the environmental responsibilities that come with them.

Naftosense's ethanol leak detection system arrives at precisely the right moment. It gives producers and refiners a reliable way to manage risk, stay compliant, and demonstrate leadership in an industry that demands both innovation and accountability.
