The level of a liquid under pressure can be determined using___________________?
Correct answer: B. Differential pressure manometer
- A. Bubbler system
- B. Differential pressure manometer
- C. Diaphragm box system
- D. Air-trap system
Explanation
A differential-pressure manometer measures the pressure difference between the liquid side and the reference side; this difference is proportional to liquid head and hence level. The vessel pressure is cancelled when both pressures are connected correctly.
