Project description: This project is a set of sonic nozzle method gas flow standard device constructed by Sinopec Changling Branch according to needs. Complete structure mining
Designed with a tiled structure. Compatible pipelines use push-pull tube replacement, which is simple and convenient. Air passes through front and rear straight pipe sections, meter clamps, stagnation
The container, the sonic nozzle and the manifold enter the vacuum pump. The microcomputer automatic verification control system is adopted, and the verification special software independently developed by our company is used to complete
The automatic verification of the flow meter can reach the verification and calibration of the critical flow sonic nozzle junction gas.
