Answer to Question 1

ANS: B
On pressure-compensated flowmeters, the needle valve controlling gas flow out of the flowmeter is located distal to the Thorpe tube. This arrangement allows the pressure in the indicator tube to be maintained at the source gas pressure, which ensures an accurate estimate of flow.

Answer to Question 2

ANS: D
There are two types of flow restrictors: fixed-orifice and adjustable, multiple-orifice models. The adjustable, multiple-orifice flow restrictor uses a series of calibrated openings in a disk that can be adjusted to deliver different flows.
