1. Test bench is consisted of 4 separate testing units, which can test 4PCS gas meters simultaneously, it is high efficient;
2. Test bench adopts single chip microcomputer, high accurate A/D converter and accurate sensor technology, each meter displays pressure loss separately. The testing results are intuitionistic and reliable;
3. No load flux and testing-point flux can be adjusted by accurate pressure-reducing valve and rotameter; No-load running time, testing time and result limit can be set by keyboard and be kept, test bench has data-save function when power is cut off;
4. The testing process is controlled by single chip microcomputer, and test results are displayed by relevant LED;
1. Flux range: 0.1-1m3/h
2. Senor range: 0-500Pa, resolution: 1Pa;
3. Testing time range: 0-999s;
4. Result limit range: 0-100Pa.
