Answer to Question 1

ANS: D
This floating movement occurs because the source gas must pass through the indicator tube be-fore it reaches the needle valve.

Answer to Question 2

ANS: C
A Bourdon flowmeter is actually a reducing valve that controls the pressure gradient across an outlet with a fixed orifice.
