GLTV3 reed switch type water fuel level sensor, it is done by sealed reed switches positioned inside the main shaft of the sensor. A float with built-in magnets then triggers the reed switch relays, generating a potential-signal with resistance, current, or voltage value that increases or decreases according to the fluid level, then give the signal to the gauge via wires, which shows the right level reading by pointer. In the whole reed switch level sensors,the float is the only moving part of the sensor,thereby minimizing potential mechanical failures to get the precision measurement.
