The Water-in-Fuel Sensor/Detector performs water detection in fuels (Jet Fuel, Diesel Fuel, Gasoline, Petrol). Water-in-Fuel Sensors are used in fuel filters, fuel/water separator, fuel refining, fuel analysis, and fuel management for engine protection in heavy vehicles such as truck, automotive, heavy equipment, ship marine, industrial and agricultural diesel engines. Diesel fuel filter/water separator systems are more popular. Fuel analysis is very important part of the refining process. By continuously monitoring the free water and suspended solids in fuels, operations can immediately detect inefficiencies or failures in filters, coalescers and separators and possible contamination from other sources.

What happens when Water in Fuel

Water in fuel is an inescapable problem for all types of engines. The result of water in fuel contamination is engine and fuel system parts damage. The cost can be extensive in terms of money and time. Water and contaminants have a direct impact on the service life and performance of engines. Besides decreasing engine life -water and contaminants are abrasive to fuel system and engine components. Water can seriously damage engine components and drastically increase down time and maintenance costs.

Clean fuel is essential for efficient , full-power engine performance. It should be handled carefully to avoid possible contamination that can prematurely plug fuel filters and cause even further, more serious damage within the engine’s fuel system.

How come Water in Fuel

The cause of water in fuel contamination can be linked to so many problems such as contaminated or poorly maintained fuel supply outlets , condensation in the fuel tank, fuel separation, water ingress and in some cases in developing countries we have found fuel has been stolen and replaced with small amounts of water .

The natural properties of diesel fuel make moisture related problems more critical in diesel equipment. Diesel fuel is heavier than gasoline, therefore the volatility (ability to vaporize) of diesel fuel is much lower than gasoline This lower volatility allows air and moisture to infiltrate the diesel fuel in both vehicle and bulk storage tanks much faster than gasoline. Water condensation in diesel fuel storage tanks is a routine problem that must be solved by all users of diesel fuels. The longer the fuel is stored, the larger the problems become.

How Water in Fuel Detector works

The Water-in-Fuel Sensor uses the difference of electric conductivity through water and diesel fuel by 2 electrodes. Water-in-Fuel Sensor is normally installed in the fuel filter and when the water level in the water separator reaches the warning level, the Water-in-Fuel Sensor send an electrical signal to the ECU or to dashboard (lamp). The Water-in-Fuel Sensor is used especially in the Common Rail engines to avoid the unit injector damage.

Applications of Water in Fuel Detector/Sensor

Water-in-Fuel Sensors are normally used for Fuel Management applications to find and separate water in fuels. Diesel fuel filter/water separator systems are more popular, as they used in vehicles and rail engines. Fuel management is required to avoid the damage of vehicle engines due to water in fuel. Water-in-Fuel Sensors are designed for use in truck, automotive, heavy equipment, marine, industrial and agricultural diesels.
