Luoyang Metrology and Testing Institute

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 ~ DN250

Flow range: air 1-5000Nm3 / h

Project description: This project is a set of standard device for gas flow of sonic nozzle method, which is constructed by Luoyang Metrology and Testing Institute according to needs. Complete structure mining
Designed with turntable and flat-panel structure. The air source is a vacuum pump, and the standard device is a sonic nozzle. The atmosphere passes through the front and rear straight pipe sections and clamps the meter
Set, stagnate containers, sonic nozzles, and manifolds into the vacuum pump. And adopt microcomputer automatic verification system, can carry out the inspection of various gas flow meters
Scheduled work.
