Regarding the installation of orifice plate flow meters
Thread Content
There is a standard: the gasket used to clamp the orifice plate must not protrude into the inner wall of the pipe after clamping. My understanding is that after clamping and deformation, there should be no parts of the gasket that block the channels; I’m not sure if this understanding is correct
It’s not the fear of obstruction, but rather the concern that it might affect the flow pattern of the fluid and thus influence the tear flow measurement values.
Yes, otherwise it will interfere with the flow phase of the fluid, leading to inaccurate measurements.
It should be like that; I remember that orifice plates have a pressure curve, and what is measured is the pressure difference before and after the orifice plate
Going forward, those with RJ sealing surfaces will not have this problem, as the sealing surface and the orifice plate are integrated together
Are gaskets used in orifice plate flow meters?
