摘要
The proposed device for testing, verification, calibration, and metrological certification of gas meters contains a gas flow rate meter with a bell chamber suspended within a vessel filled with transformer oil, a measuring rule with cursors that is arranged at the bell chamber, a photodetector module that is installed at the casing of the flow rate meter, an air supply unit with a gate valve, a gas flow rate controller, pressure and temperature transducers, a unit for data acquisition and transmission, a computer, and a printer. For controlling the operations of the device, an additional control console can be used. The additional control console is connected to the unit for data acquisition and transmission in parallel with the computer.
