MOBILE VERIFICATION UNIT FOR GAS DISTRIBUTION STATION METERS Russian patent published in 2023 - IPC G01F25/10 

FIELD: measuring technology.

SUBSTANCE: invention can be used for verification and calibration (control of metrological characteristics) of gas meters of gas distribution stations, including gas dispensers and general industrial gas meters of municipal and industrial enterprises. The mobile calibration unit for meters of gas distribution stations contains a gas cylinder system, a reducing unit, a gas dispenser with a gas metering system, a flexible hose. The inlet of the reducing unit is connected to the gas cylinder system, and the outlet is connected to the gas dispenser with a gas metering system. In case of verification or calibration of a general industrial gas meter of a gas distribution station, the outlet of the gas dispenser with the gas metering system is connected by a flexible hose with a branch pipe of the gas distribution station, the output of which is connected through a drain valve to the calibrated gas metering unit of the gas distribution station and the valve of the supply line.

EFFECT: uninterrupted supply of gas during metrological verification and calibration of its metering systems in the process of functioning of gas supply systems of enterprises.
