Application
For applications such as measure flow or level using a differential pressure transmitter
or gauge with a calibration facility.
Using the Differential Filter 3 Valve
In normal operation the “isolate” valves are open while the “equalise” valve is closed.
This provides a differential pressure medium to the pressure gauge or transmitter.
To zero the instrument, first close the downstream “isolate” valve then open the
“equalise” valve and adjust the zero settings on the instrument.
To remove the instrument, first close both “isolate” valves, then unscrew the vent (drain)
plugs normally fitted to the instrument to relieve pressure between the manifold
and the instrument.
