Problems with gas mass flow meters
Thread Content
There was a Brooks gas mass flow meter on site, with an operating pressure of 6 kilograms, but it was damaged as soon as gas was first fed into it. The pressure of the gas feed did not exceed the specified value; the manufacturer suggested that perhaps no gas was flowing behind the flow meter at the time of feeding, resulting in a high instantaneous pressure difference that damaged the diaphragm. Is this kind of explanation reasonable?
It’s definitely unreasonable. To analyze the reasons, one should first check whether the installation method is correct, whether the power supply and wiring are proper, whether there is a certification certificate for calibration (authentication by a metrological authority), whether configuration settings are required, whether those settings are correct, whether pressure is recorded during operation, whether any other actions are performed on the pipelines before feeding (such as purging the pipelines), whether there is a gas-liquid mixture, whether the medium is flowing through the pipelines, and whether there are any other reference points for observation. . . . . . . Wait, just analyze and rule things out step by step.
The manufacturer is really careless, haha/
