What is the purpose of the pressure gauge at the pump outlet?

What is the purpose of the pressure gauge at the pump outlet? I’ve seen some design schemes where the pressure gauge is placed in front of the check valve, while in others it’s placed behind it. Which one is more appropriate?
Monitoring the fluid pressure and the operation of the pump should be done after the check valve, so that it is possible to determine whether both the pump and the check valve are functioning properly.
Measure the pump outlet pressure to monitor whether the pump is operating properly; it should be installed in front of the check valve
So is it before the check valve or after it? Which one would be more suitable?
The pressure gauge at the pump outlet is used to determine whether the pump is delivering flow, and to check if there is pressure in the pump during maintenance.
Before the check valve, measure the outlet pressure of the metering pump
Installed before the check valve, it measures the outlet pressure of the pump, which is more useful for analyzing the pump’s operating condition
Measure the pump outlet pressure; it should be taken in front of the check valve
Installed between the check valve and the pump; refer to page 3-37 of the \"Chemical Process Design Manual (Third Edition)\"
So what would be the effect if it were placed behind a check valve?
Installed between the pump and the check valve to measure the outlet pressure of the pump.
