Project description: This project is a set of standard equipment for gas flow rate of sonic nozzle method, which is constructed by Guangzhou Energy Testing Institute according to needs. Complete knot
The structure adopts a tiled structure design. Compatible pipelines are simple and convenient with a push-pull tube change. The air source uses 2BEA type vacuum pump, the standard device is
Sonic nozzle. The microcomputer automatic verification control system is adopted, and the verification software developed by our company independently completes the automatic verification of the flow meter.
Verification and calibration of gas junctions with critical flow sonic nozzles is achieved.
