Pressure Gauge

A pressure gauge is a device used to measure the pressure of a gas or liquid within a piece of equipment they are connected to. They are usually found in a range of equipment including pipework, filters, pressure vessels, and Pumps.

When a pressure gauge is connected to the inlet of a pump and the discharge of a pump the difference between the two figures is what the pump is producing. Pumps produce a differential pressure within a system meaning whatever pressure is received at the inlet, the pump will produce its design pressure and flow in addition meaning the outlet pressure will be equal to the Inlet pressure, plus the pressure produced by the pump.
