Series PFG2 Process Filter Gage

Indicates Process Filter Status, In-Line or Bottom Connect Mounting

The Series PFG2 Process Filter Gage is designed for determining the state of an inline filter. The differential pressure indicator determines the pressure drop on either side of a filter through its 1/8" female NPT pressure connections, and relates the value to one of three zones: clean (green), change (yellow), or dirty (red). The Series PFG2 is perfectly suited for 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. The PFG2 can be connected in-line through the side process connections, but can also be directly mounted through the outlet/inlet.
