# Gas meters and volume conversion devices — Accuracy classes and maximum permissible errors for trade measuring instruments (EU MID)

For Gas meters and volume conversion devices, annex is Annex IV (MI-002); accuracy class is 1,5; condition is temperature conversion, 30 °C range around specified temperature; maximum permissible error is MPE increased by 0,5 %; scope or member state option is For a gas meter with temperature conversion, which only indicates the converted volume, the MPE of the meter is increased by 0,5 % in a range of 30 °C extending symmetrically around the temperature specified by the manufacturer that lies between 15 °C and 25 °C, recorded from its source on 2026-08-05.

- **Instrument type:** Gas meters and volume conversion devices
- **Annex:** Annex IV (MI-002)
- **Accuracy class:** 1,5
- **Condition:** temperature conversion, 30 °C range around specified temperature _(our reading, not quoted from the source)_
- **Maximum permissible error:** MPE increased by 0,5 %
- **Scope or member state option:** For a gas meter with temperature conversion, which only indicates the converted volume, the MPE of the meter is increased by 0,5 % in a range of 30 °C extending symmetrically around the temperature specified by the manufacturer that lies between 15 °C and 25 °C. _(our reading, not quoted from the source)_

## What the source says

> For a gas meter with temperature conversion, which only indicates the converted volume, the MPE of the meter is increased by 0,5 % in a range of 30 °C extending symmetrically around the temperature specified by the manufacturer that lies between 15 °C and 25 °C. Outside this range, an additional increase of 0,5 % is permitted in each interval of 10 °C.
