Belite Introduces Safety Enhancing Fuel / Water Discriminator


Belite RADIANT Technology released a new product that enhances safety by alerting the pilot to fuel exhaustion or water contamination.

The new RADIANT Fuel / Water Discriminator will instantly tell the pilot or vehicle operator if the fuel line is empty or if liquid water is detected in the fuel line. This innovative product is based on patent pending technology and is installed in the fuel line. It increases pilot safety by alerting a pilot to switch tanks in the event of fuel exhaustion on one tank and also provides a positive and immediate indication if liquid water is present in the fuel line.

The product is easily installed through the use of standard tubing barb adapters.  It requires a power source and has two output lines.  One line is active when normal fuel (for instance, MoGas or 100LL) is present in the line.  This line reverts to inactive if fuel is no longer detected in the line.  The second line only becomes active when water is detected.  A typical panel installation will have 3 lighted indicators for each fuel discriminator:  Presence of Fuel (green LED); Absence of Fuel (red LED); Presence of Water (red LED).  Belite offers a prebuilt indicator display head for ease of installation.

The liquid never comes into physical contact with any sensors, which helps provide additional safety to the installation.  The fuel sampling tube within the device is built from a material which is impervious to most known liquids and is designed to withstand temperatures from -100° to +400°F (-70° to 200°C), with a maximum pressure of 300 psi (20 bar) at 72° (22°C).  The normal operating range of the product is -20°C to +50°C.  The product carries a one year warranty, but is expected to last indefinitely in normal usage, requiring no maintenance.

James Wiebe, CEO of Belite, said: “I’ve been working on new approaches to fuel measuring systems for years, and this particular safety enhancing product has been a very important goal for a long time. Water in fuel causes accidents and deaths every year, so if pilots are given an alarm when water is present, or when fuel is exhausted, safety is clearly increased.”

Another version of the product without the water detection feature is useful for operators who simply wish to be alerted when a fuel line runs dry.

Pre-orders will be accepted immediately at  First shipments of the product are slated for Q4 of this year (2017).
