Process Filter Gauges

Process Filter Gauge, Series PFG is designed for applications requiring a simple, low cost differential pressure indicator for filter status check or other pressure drop situations.
The Series PFG Process Filter Gauge is designed for determining the state of an in-line filter. The differential pressure indicator determines the pressure drop on either side of a filter through its 1/4" female NPT pressure connections, and relates the value to one of three zones: clean (green), change (yellow), or dirty (red). The Series PFG is perfectly suited for filter applications, line loss, valve drop, and many other differential pressure applications where a simple indicator is needed.
