Answer to Question 1

ANS: A
Compared with the flow restrictor and the Bourdon gauge, the Thorpe tube functions as a varia-ble-orifice, constant-pressure flowmeter device, so increasing the size of the orifice increases the gas flow.

Answer to Question 2

ANS: D
The Bourdon gauge is the best choice when a flowmeter cannot be maintained in an upright posi-tion.
