As the title suggests, also, if there are sand holes in the body of the orifice plate flow meter, is it necessary to shut down operations in order to repair them?

It contains hydrogen, and the pressure needs to be increased to 20 MPa

The orifice flow meter is equipped with hand valves at both the inlet and outlet, which affect the flow pattern of the fluid and lead to inaccurate measurements
