Installation & Use Of Differential Pressure Gauges

Ensure that the differential pressure gauge range, maximum line pressure and materials of wetted parts are correct for the application.  As the gauge is a delicate instrument it should not be mounted in a position where it is vulnerable to damage.  In cases where there may be a sudden pressure surge on start-up, it is necessary to fit isolating valves on each leg  and link the pipes between each valve and the differential pressure gauge by a line with a third valve to use for balancing.
