Water in fuel sensor

May 2021 Sensors & Transducers

A water in fuel sensor is a device that detects the presence of water in a fuel system. They are often used for control in the event the moisture content reaches a predetermined set-point.

What is the difference between moisture and free water measurements?

Moisture in a fuel is often detected at low levels and sensors have been designed to determine an increase in moisture levels over time. Moisture meters normally respond very slowly and are limited in their range (only measuring moisture) but free water measurements enable operators to identify when other problems have occurred such as water break out.

Eesiflo International’s Easz-2 can measure both gradual moisture increases over time as well as the presence of free water in real-time. Operators are provided with the added advantage of knowing an event has occurred e.g. a sudden increase in water droplets in the fuel pipe during operation. Such measurements are taken once per second.

The Easz-2 moisture in fuel detector is a modern development which performs highly repeatable and accurate online measurements of the water content in fuel, with the option to transmit readings through traditional analog signals or via Modbus. In many instances, fuel is not normally supposed to contain any moisture and quality checks through manual sampling are not always sufficient to determine contamination levels. The Easz-2 was designed to provide users with continuous data about the actual state of the fuel in real-time. Armed with immediate sensor data on the moisture contamination in a flow fuel stream, it is possible to correct process anomalies before they become too problematic.

The Easz-2 is currently being manufactured and supplied to standard off-the-shelf applications, but is not limited by its standard design. The product can be configured to meet different requirements through the addition of add-on boards and custom firmware.
