Tianjin Huashui Instrument Factory

Project Name: Standard Device for Gas Flow at Normal Pressure and Sonic Nozzle

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

Test pipeline range: DN25 ~ DN200

Flow range: air 1-4000Nm3 / h

Project description: This project is a set of standard equipment for gas flow at normal pressure and sonic nozzle method constructed by Tianjin Huashui Instrument Factory according to needs. Complete structure
Adopt tile structure design. Compatible pipelines are simple and convenient with a push-pull tube change. The air source uses a vacuum pump, and the standard device is a sonic jet
mouth. The air enters the true pump through the front and rear straight pipe sections, the meter clamp device, the stagnation container, the sonic nozzle, and the manifold. Microcomputer automatic verification control system
System, mainly used for the verification of gas flow meters.
