Orifice plate flow meter
Thread Content
In practical use, when the orifice plate flow meter operates at full load, the flow rate exceeds the rated range by 175% – is this due to a low designed flow rate? How should it be adjusted? Do I need to replace the orifice plate?
It should not be necessary to replace the orifice plate; simply replacing your differential pressure transmitter will suffice.
Generally, there’s no issue with selecting the flow meter; you should carefully check the pipelines for any problems.
175% above the range – was this value read from the gauge? Has it been squared rooted? What is the loop current? Generally, it’s because the parameters of the transmitter haven’t been set correctly
