Meter Verification

To maintain registration under the CHPQA Programme, meters need to be verified on a regular basis. As stated by the guidance: “All meters that are used for self-assessment that are not independently calibrated by others (such as gas or electricity supply companies) should be regularly calibrated or validated in accordance with a calibration schedule.

A typical verification takes 1½-2 hours. Equipment that may be used includes: a portable ultrasonic flowmeter, infra-red thermometer and laptop with download software.

Following a successful verification, a certificate is issued which shows how the meters performed during the verification.

Heat Meters
Heat meters are normally supplied as a package comprising of a flow meter, a pair of temperature sensors and a calculator; verification of components such as transducers, transmitters and computations should occur every 2 years.

Electricity Meters
Electricity meters on individual power outputs require verification and accuracy checks to be carried out at 5, 10 or 15 year intervals depending on the metering system installed.

Gas Meters
Meters with moving in-pipe primary flow elements, such as turbine meters and Gilflow meters should be carried out every 5 years.
