Why can’t the flow orifice be installed upside down?

Flow meter /

A correctly installed orifice plate should have the constriction facing the direction of the fluid. The fluid contracts locally at the throttling center, increasing the flow rate and reducing the static pressure, so a static pressure difference is generated before and after the orifice plate, and this pressure difference has a certain functional relationship with
