High Accuracy Fuel Level Sensor

The FLS-H is a fuel sensor with high quality,designed for heavy duty trucks,buses and off road vehicles.It could be easily adapted to different types of tanks and can be delivered with customized sensor length, various fittings and output signal.The measurements are done by a series of reed switches positioned inside the level tube,a float with built in magnet moving up and down when fluid level changes, 
would trigger the reed switches inside the tube respectively, thus, generate a potential  free resistance signal with a Ohm value to indicate the change of fluid level.The switch contacts are hermetically sealed in the inert gas,and operated by a magnet,
 it is more reliable than the traditional resistive fuel level sensor.
