Fischer NC57 - Capacitive liquid level transmitter - diesel, water, sewage

Working Principle:

A metal rod need to be mounted at a fixed distance from the tank wall. This forms a capacitor when charged with AC voltage. When the rod is immersed in a liquid media, the capacitance value become function of immersed length.

With probe fixed vertically downward, immersion length is proportional to the liquid level. Hence, capacitance of the probe become function of liquid level.
An electronic module inside NC57 converts the capacitance value to level measurement and transit as linear analog signals in voltage or current form.
