What consequences will occur if an orifice plate is installed on a pipe in the wrong orientation?
Standard orifice plates have chamfers; installing them in the reverse direction results in a lower flow rate. A two-way flow orifice plate has no chamfers, and the orifice plate itself has no distinction between a \"front\" and a \"back\" side. @jiaguoyun
Since the orifice plate is a throttling element, its measurement principle is determined based on the relationship between the pressure difference before and after it and the flow rate. The greater the pressure difference, the greater the flow rate. When installed reversely, structural reasons cause the measured pressure difference to decrease, resulting in a lower flow rate reading.
When the orifice plate used for measuring flow rate is installed in reverse, the flared end of the orifice plate faces the fluid flow, resulting in a reduced pressure difference across the plate and thus an underestimated flow rate.
