Problems solved by technology

The detection device using this test method has the advantages of accurate testing and quantitative detection. It is not necessary to know the flow rate value of the gas relay to be calibrated before the test, but its biggest disadvantage is that the equipment is heavy and different caliber gas relays need to use different Caliber test pipeline, one device cannot meet the existing gas relay, a user may need to purchase 2 to 3 sets of the same gas relay detection equipment, if the gas relay under test is modified or a new product appears, the equipment hardware needs to be improved, Limits the adaptability of the device
