Vortex flow meter
Thread Content
Why does the vortex flow meter display a flow rate that is always lower than the actual flow rate? The calibration of the flow meter is correct; what issues could be causing this problem?
How did you obtain this actual traffic volume?
Check if your flow meter has temperature and pressure compensation; if not, verify whether the density setting is correct
There are too many possible reasons. Consider both the design and installation aspects. What do you mean by calibration? Was it calibrated at a qualified facility? If not, please do not say that the flowmeter has been calibrated.
Same question: where does the actual traffic come from?
There are many reasons: vibration, insufficient straight pipe sections, electromagnetic interference, etc. First, it is necessary to determine how the actual flow rate is generated.....
How do you know the actual traffic must be high?
Check the setting of the K coefficient, and also pay attention to whether the pipeline installation meets the requirements; density is also very important.
There are too many reasons; it’s better if you describe the operating conditions so that everyone can give you some suggestions. When looking for reasons like this, just give a brief description and let others help find them. It’s simpler that way – after all, you can’t expect everyone to list all the possible reasons for you, as that would be way too much
There are many reasons; please provide parameters such as operating conditions so that the issue can be analyzed.
