The qbig GmbH, a subsidiary of the gas- transport Nord GmbH, builds a new high pressure calibration facility for gas meters in the north west of Germany. The unique selling point of this calibration facility is that meters with a diameter up to 20" and a pressure range from 8 up to 55 bar can be testest bidirectionally in one setting. This results in a significant reduction of the calibration time of bidirectionally operated meter runs as used in underground storage.
The calibration facility is manufacturer independent and is used for testing, verification and calibration of turbine gas meters and ultrasonic gas meters. It will be a state-approved test facility. Additionally, it will be accredited according to DIN EN ISO/IEC 17025. The reference standarts will be derived from the european standard for high pressure natural gas of the Federal Institute of Physics and Metrology (PTB).
