Answer:C
What type of pressure gauge uses a U-shaped tube filled with liquid as its sensing element?
A. Bourdon tube gauge B. Diaphragm gauge C. Manometer gauge D. Bellows gauge
Explanation: Manometer gauges use a U-shaped tube filled with liquid, such as mercury or water, to measure pressure. The pressure exerted on one end of the tube causes the liquid to rise on the other end, indicating the pressure.
