A large water filter occasionally plugs with debris, and operations wants to have a gauge indication of this plugging.
Since plugging of the filter will result in greater differential pressure drop across it for any given amount of water flow through it, measuring pressure drop with a differential pressure gauge will provide a simple indication of filter plugging.
How do you connect the tubes (HP & LP impulse lines) between the differential pressure gauge and the filter (the two “taps” shown on the pipes are ready to connect to instrument tubing) so that the gauge registers positive pressure as the filter becomes plugged.
