Accurate & Reliable Fuel Level Sensors for Vehicles, Generators & Industrial Tanks

Leading manufacturer of CANBUS, J1939, and Analog output sensors. High-resolution (5mm) measurement for Generators, Fleet Management, and Marine tanks.

Overview Content

Fuel level sensors are critical components for monitoring fuel consumption, preventing fuel theft, and ensuring safe operation of vehicles and generators. Bluefin fuel level sensors are based on the design of "float+Reed Switch" and “float+TMR", and output signal variants of analog resistance/voltage/current, or CANBUS(J1939)/RS485 digital type, which are most popular in industries for diesel, gasoline, oil, and water tanks.
