Answer:C
Which type of level gauge works on the principle of radiation?
A. Sight glass level gauge B. Float level gauge C. Nuclear level gauge D. Guided wave radar level gauge
Explanation: Nuclear level gauges work on the principle of nuclear radiation. They emit low-level radiation that passes through the liquid and is detected on the other side of the tank. The amount of radiation detected is used to determine the level of the liquid.
