For the same flow meter, when measuring different media, is the flow measurement still accurate?
Thread Content
We have a compressor, and because the composition of the medium keeps changing, its molecular weight also remains variable. For a differential pressure flow meter, is the flow rate measured in this case still accurate?
It should be prohibited, I’m just an outsider who doesn’t understand anything
The molecular weight is converted to the corresponding density for correction
See what kind of traffic information is available. If the operating temperature and pressure remain unchanged, as well as the volumetric flow rate, then the weight flow rate/mass flow rate will change.
If the density difference of the media is small, the impact is minimal.
The flow rate measured under these conditions is approximate
If the components change, the measurement will definitely be inaccurate.
1. Replace the flow meter; by using mass and density data and performing external conversions, obtain the volume measurement value. 2. Apply gas density compensation to the volume measurement value provided by the flow meter
