Do you have concerns about the amount of your gas bills? Do you suspect your meter is faulty? Find out what the procedure is for metrological and technical assessments of bellows-type gas meters.
A gas meter technical assessment is a technical assessment carried out under the supervision of the Office of Weights and Measures. Its purpose is to determine whether the meter is measuring gas consumption correctly (in accordance with its accuracy class) and whether its mechanism has been tampered with (e.g. by breaking seals or using neodymium magnets).

How does the examination work? Step by step?
The procedure is rigorous and consists of three main stages:
External inspection: Specialists check the condition of the enclosure, the integrity of the verification and installation seals, and look for signs of any mechanical damage or exposure to magnetic fields.
- Metrological testing: The gas meters are placed on a calibration stand, where air with strictly defined parameters is passed through them. Their readings are compared with a precise standard to calculate the measurement error
- Technical assessment: If any irregularities are detected, the meter is opened. The condition of the bellows, internal and external components is verified, with particular attention paid to unauthorised tampering
