What statement is true concerning the operating principle of a liquid level sensing and transmitting system of the capacitance type?

Question

Accepted Answer

The capacitance method is generally used with non-conductive liquids and works on the principle of the substantial difference between the dielectric constant of air and that of the liquid in the tank.

Answer
