Department for primary standarts of natural gas flow rate

Head of Department: Mr. Yuiriy Borodin, e-mail:

The main task of the Department is the reproduction and transfer provision of units (volume and volumetric flow) for natural gas to operating standards of calibration rigs of Metrological Centre and oil and gas enterprises.

Primary standard of volume and volumetric flow rate for natural gas, bell type

Standard installation for calibration and verification of flow rate operating standards for natural gas and transfer standard – rotary-piston prover IRPP, manufactured by Instromet International.

Operating medium – air or natural gas.
Operating flow rate – 0.1 … 400 nm³/h.
Operating excessive pressure – 1.2 kPa.
Uncertainty – 0.07-0.09%.
