Meter Reading and Measurement Flashcards

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

Answer: Cubic feet (CCF or MCF)

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

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

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

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

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

Answer: To convert raw meter dial readings into actual gas volume consumed

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.

What is an Automated Meter Reading (AMR) system?

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

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

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

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

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

Why must a gas meter be installed in a level, upright position?

Answer: To ensure proper diaphragm movement and accurate measurement

Diaphragm meters must be installed upright and level to ensure the diaphragm chambers move correctly and displacement volumes are accurately measured.
