Top 10 Questions for Field Mechanical Meter Tester Interview

1. Explain the process of calibrating a mechanical meter?

• I would first gather the necessary equipment, including a calibration standard, a pressure gauge, and a flowmeter.
• I would then disconnect the meter from the system and connect it to the calibration standard.
• I would use the pressure gauge to measure the pressure at the inlet and outlet of the meter, and the flowmeter to measure the flow rate.
• I would then adjust the meter’s calibration until the readings from the pressure gauge and flowmeter matched the readings from the calibration standard.
• I would finally reconnect the meter to the system and verify that it was operating properly.

2. What are the different types of mechanical meters?

Diaphragm Meters

• Operate on the principle of a flexible diaphragm that moves back and forth in proportion to the volume of gas flowing through the meter.

Rotary Meters

• Use a rotating element within the meter to measure the volume of gas flowing through.

Turbine Meters

• Employ a turbine that spins in proportion to the velocity of the gas flowing through the meter.

3. What are the most common problems that you encounter when testing mechanical meters?

• Clogged or dirty meters
• Damaged or worn diaphragms
• Leaking seals
• Incorrect calibration

4. What are the safety precautions that you must take when testing mechanical meters?

• Wear appropriate safety gear, including gloves, safety glasses, and a hard hat.
• Ensure that the area where you are working is well-ventilated.
• Never smoke or use open flames near the meter.
• Be aware of the potential for gas leaks and take appropriate precautions.

5. What are the different methods for testing mechanical meters?

Bench Testing

• Involves removing the meter from the system and testing it on a bench.

In-Situ Testing

• Testing the meter while it is still installed in the system.

Non-Intrusive Testing

• Using ultrasonic or other non-invasive methods to test the meter without removing it from the system.

6. What are the different types of test equipment that you use to test mechanical meters?

• Calibration standards
• Pressure gauges
• Flowmeters
• Ultrasonic testers
• Non-intrusive testing devices

7. How do you interpret the results of a mechanical meter test?

• I would first compare the results of the test to the manufacturer’s specifications for the meter.
• I would then determine if the meter is operating within the acceptable tolerance range.
• If the meter is not operating within the acceptable tolerance range, I would recommend that it be repaired or replaced.

8. What are the benefits of regular mechanical meter testing?

• Ensures that the meter is operating accurately and reliably.
• Helps to identify potential problems early on, before they can cause major damage or downtime.
• Can help to save money by reducing the likelihood of overpaying for gas or other utilities.

9. What are the challenges of mechanical meter testing?

• Testing can be time-consuming and labor-intensive.
• It can be difficult to access meters that are located in difficult-to-reach locations.
• Testing can be hazardous, as it involves working with gas or other hazardous materials.

10. What is the future of mechanical meter testing?

• Non-intrusive testing is becoming increasingly popular, as it offers a faster, safer, and more cost-effective way to test meters.
• Automated testing systems are also being developed, which can further reduce the time and labor required to test meters.
