Which type of level gauge works on the principle of capacitance measurement?
A. Sight glass level gauge B. Float level gauge C. Ultrasonic level gauge D. Capacitance level gauge
Explanation: Capacitance level gauges work on the principle of capacitance measurement. They measure the change in capacitance between a probe and the liquid surface and use this measurement to determine the level of the liquid.
