0.016 m3/h～6 m3/h Gas Meter Test Bench ( Domestic gas meter)
Gas Meter Test Bench MCGB001
- Adopting serial comparison method
- Can test several different kinds of diaphragm gas meter
- Can be operated by PC software
- Flow range: 0.016m3/h – 6m3/h / 0.06m3/h-40m3/h
- Total uncertainty: ≤0.5%, k=2
Feature
1) Adopt Serial comparison method to test several different kinds of diaphragm gas meter.
2) Use VSBA Sonic nozzle to meet Qmax,0.2Qmax,Qmingas meter flow point measurement.
It is convenient to change and clean nozzle regularly. (patent No.:20110237008.6)
3) Could accurately test temperature, pressure etc. and calculate error in time, guarantee
device stable and accurate Ø
4) Adopt negative pressure method to ensure gas flow passed through to reach Critical flow state.
5) Test system could test automatically under control of PC software, meanwhile could save, print,
analyze and statistic etc.
6) Also test manually gas meter without cursor .
7) Graceful appearance, fine art-work,durable structure
