Generally, a vacuum gauge is installed only at the inlet; it seems unnecessary to install a pressure gauge there! ? For reference only! ! ! !
Generally, a local pressure gauge should be installed after a standard design pump, but I haven’t heard of one being used before the pump. If one is to be installed, the pressure before the pump is usually negative, so a pressure gauge suitable for handling negative pressures should be chosen
Regarding the zero-level tank you mentioned, generally the pump inlet is above the liquid level, and in such cases a vacuum gauge is required； If, in other processes, the pump inlet is below the liquid level, a vacuum gauge must be installed in such cases. Installing a vacuum gauge or vacuum pressure gauge at the pump inlet helps in analyzing the cause of faults.
