Sample interview questions: Are you familiar with different types of gas meters and their installation requirements?
Sample answer:
- Diaphragm Meters:
- Most common type of gas meter.
- Measures the volume of gas passing through it by the displacement of a flexible diaphragm.
-
Requires a minimum of 18 inches of straight pipe upstream and downstream of the meter.
-
Rotary Meters:
- Another common type of gas meter.
- Measures the volume of gas passing through it by the rotation of a rotor.
-
Requires a minimum of 10 diameters of straight pipe upstream and downstream of the meter.
-
Turbine Meters:
- Often used for large-volume applications.
- Measures the volume of gas passing through it by the rotation of a turbine wheel.
-
Requires a minimum of 20 diameters of straight pipe upstream and downstream of the meter.
-
Ultrasonic Meters:
- Utilize ultrasonic waves to measure the velocity of gas flowing through the pipe.
