Question 2

Which of the following are true about a Bourdon gauge?
 
  1. It is always used with an adjustable high-pressure reducing valve.
  2. It actually senses pressure but is calibrated to display flow.
  3. It reads a flow higher than actual if downstream pressure increases.
  4. It will register zero flow when the outlet is completely blocked.
  a. 1 and 3 only
  b. 1, 2, and 3 only

Answer to Question 1

ANS: D

Answer to Question 2

ANS: B
