DEVICE FOR REPRODUCING UNITS OF MEASUREMENT FOR VOLUME, WEIGHT, AND FLOW RATE OF NATURAL GAS

摘要

The proposed device for reproducing units of measurement for volume, weight, and flow rate of natural gas when calibrating gas flow meters contains a receiving unit, a standard gas flow meter with a bell chamber, and a unit for recording and processing data. The receiving unit is designed with a possibility to control the difference of pressures at the inlet and the outlet of the unit.
