Guizhou Metrology and Testing Institute

Project name: Standard meter gas flow standard device

The main technical parameters: Device expansion uncertainty: 1% (standard table uncertainty 0.5%) (K = 2)

Test pipeline range: DN15 ~ DN80

Flow range: air 1-1000Nm3 / h

Project description: This project is a set of standard meter gas flow standard device constructed by Guizhou Provincial Metrology and Testing Institute according to need. Complete structure
Adopt skid-mounted structure design. The air source uses a high-pressure fan and enters the test tube section through a pressure-stabilizing container. And adopt advanced microcomputer automatic verification control
The system can carry out the verification and calibration of the 1.5% gas flow meter.
