RMGA Meter Reading and Measurement

Question 1

What is the unit of measurement displayed on a residential natural gas meter in the United States?

Accepted Answer

Cubic feet (CCF or MCF)

Answer

Residential gas meters in the US typically display consumption in cubic feet, billed in hundred cubic feet (CCF) or thousand cubic feet (MCF).

Question 2

What device is installed on a gas meter to measure the volume of gas passing through it?

Accepted Answer

Diaphragm meter (for residential), turbine or rotary meter (for commercial/industrial)

Answer

Residential customers typically use diaphragm (bellows) meters, while larger commercial and industrial customers use turbine or rotary displacement meters.

Question 3

What is the purpose of a meter index correction factor (or meter multiplier)?

Accepted Answer

To convert raw meter dial readings into actual gas volume consumed

Answer

The meter multiplier converts the meter's index reading into actual cubic feet or other billing units when the meter register does not display the full volume directly.

Question 4

What is an Automated Meter Reading (AMR) system?

Accepted Answer

A technology that allows meter data to be collected remotely without a meter reader walking the route

Answer

AMR systems use radio frequency or other communication technologies to collect meter data remotely, improving efficiency and reducing billing errors.

Question 5

What causes a 'fast meter' in natural gas measurement?

Accepted Answer

A meter that records more gas than actually passes through it, resulting in over-billing

Answer

A fast meter records higher volumes than actually flow through it, causing the customer to be billed for more gas than was used.
