Pressure gauge at discharge of pumps
Pressure gauge at discharge of pumps
(OP)
At the discharge of pumps,I use to locate the pressure gauges downstream from the check valves so it could help me as a reference of a malfunction of the check. I've seen other people installing the gauges right after the pump (before the check). Any comment or suggestion regarding the best location?

If you're trying to detect a malfunction of the check valve, then a gage downstream of the valve makes sense.
I'd buy cheaper gages and do both.

One has only to remember that, discarding elevation effects, and following Bernoulli's equation, the -horizontal- pipe diameter on which the gage is installed may influence the reading, by interchanging velocity head and static head.

BigInch, that's precisely the point, by changing pipe diameters one head is converted into the other changing the static pressure readings.

This gives a true reading of discharge pressure of the pump, without the effects of the check valve.
