FST700-205 Float Fuel Oil Water Liquid level sensor -- economical fuel level sensor with factory SGS authorized 

FST700-205 Fuel & Water level sensor is based on the principle of reed switch to test liquid level. When liquid level changes, the float will move up & down, the magnet built in the float will drive the reed switch, and the signal output will change immediately, liquid level change can be displayed by displayer.  Only the float is a ocomotive part in the whole products, this can minimized reduce the mechanical problem and realize accurate level testing.

Simple construction, easy installation
