Answer:C
Which type of level gauge works on the principle of thermal conductivity?
A. Sight glass level gauge B. Float level gauge C. Thermal dispersion level gauge D. Guided wave radar level gauge
Explanation: Thermal dispersion level gauges work on the principle of thermal conductivity. They have two temperature sensors that detect the difference in temperature between the liquid and the gas above it. The difference in temperature is used to determine the level of the liquid.
