How can you determine if you have a compensated Thorpe tube flowmeter?
I. The needle valve is proximal to the Thorpe tube.
II. The needle valve is distal to the Thorpe tube.
III. The ball "jumps" in the Thorpe tube when connected to 50 psi.
IV. The label states "calibrated 760 mmHg, 70 degrees F, 50 psi inlet and outlet pressure."

A compensated Thorpe tube flowmeter is designed to provide accurate flow regardless of downstream pressure changes. This is indicated by the needle valve being distal to the Thorpe tube (II), which allows for pressure compensation. The ball "jumping" in the Thorpe tube when connected to 50 psi (III) is a characteristic of how the flowmeter responds to the standard pressure. The label stating "calibrated 760 mmHg, 70 degrees F, 50 psi inlet and outlet pressure" (IV) directly indicates that the flowmeter is calibrated for specific conditions, including compensation for variations in pressure.
