Series PFG2 Process Filter Gage

Specications - Installation and Operating Instructions

Bulletin P-PFG2

The Series PFG2 Process Filter Gage is designed for determining the state of an

in-line lter. The differential pressure indicator determines the pressure drop on either

side of a lter 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 lter applications, line loss, valve drop, and many other

differential pressure applications where a simple indicator is needed.

MOUNTING

The Series PFG2 features two #10-32 UNF threaded holes in its mounting block for

easy mounting. The holes are 3/4˝ apart and located at the same level as the end

process connections. The direction of process ow 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°.

Retighten the plastic bolts to 20 to 25˝ pounds of torque. By removing the mounting

block, the PFG2 can be directly mounted through the outlet/inlet connections on the

bottom of the unit.

MAINTENANCE

Upon nal installation of the Series PFG2 Process Filter Gage, no routine maintenance

is required. A periodic check of system calibration is recommended. The Series PFG2

is not eld serviceable and should be returned if repair is needed (eld repair should

not be attempted and may void warranty). Be sure to include a brief description of the

problem plus any relevant application notes. Contact customer service to receive a

return goods authorization number before shipping.
