Gansu Yinguang Group ( 805 Factory)

Project Name: Sonic Nozzle Gas Flow Standard Device

The main technical parameters: Device expansion uncertainty: 0.3% (Sonic nozzle uncertainty 0.2%) (K = 2)

Test pipeline range: DN25 ~ DN200

Flow range: 1-1600Nm3 / h

Project description: This project is a set of standard device for gas flow of sonic nozzle method constructed by Yinguang Group Company according to needs. The entire structure is flat
Paving structure design. Compatible pipelines use push-pull tube replacement, which is simple and convenient. The air source uses a vacuum pump, and the standard device is a sonic nozzle. air
It goes into the vacuum pump through the front and rear straight pipe sections, the meter clamping device, the stagnation container, the sonic nozzle, and the manifold. Using microcomputer automatic verification control system, the main
To be used for the verification of various gas flow meters.
