D. Ultrasonic level gauge
Answer:C
Which type of level gauge utilizes the principle of buoyancy for measuring liquid levels?
A. Sight glass level gauge B. Magnetic level gauge C. Float level gauge D. Ultrasonic level gauge
Explanation: Float level gauges work by utilizing the buoyancy principle where the buoyancy force is proportional to the weight of the liquid displaced by the float.
