Process Filter Gage Determines State Of In-Line Filters

dwyer1226.jpg

Dwyer Instruments new Series PFG2 process filter gage is designed to determine the state of an in-line filter. The differential pressure indicator determines the pressure drop on either side of a filter through its 1/8-inch female NPT pressure connections and relates the value to one of three zones: clean (green), change (yellow) or dirty (red).

The Series PFG2 suits filter applications, line loss, valve drop, and many other differential pressure applications where a simple indicator is needed. The direction of process flow is indicated on the dial, with the arrow pointing to the low pressure port. In order to change the high- and low-pressure connections, simply remove the indicator from the mounting base and rotate 180 degrees. The PFG2 can be connected in-line through the side process connections but can also be directly mounted through the outlet/inlet connections by removing the mounting block.
