Dwyer Series PFG User manual

Brand: Dwyer

Model: Series PFG

Type: User manual

Dwyer Series PFG is a versatile tool designed to simplify the monitoring of filter performance and differential pressure in various industrial and commercial applications. Here are some of its key capabilities and potential use cases:

Filter Monitoring: The PFG can be connected to an in-line filter to monitor its condition. Its differential pressure indicator provides a clear visual representation of the pressure drop across the filter, helping users determine when filter replacement is necessary. This can help prevent costly downtime and equipment damage caused by clogged filters.
Differential Pressure Measurement: The PFG can also be used to measure differential pressure in applications such as line loss, valve drop, and other situations where a simple and reliable pressure indicator is required. Its ability to measure pressure drops up to 300 psig makes it suitable for a wide range of industrial processes.

Specifications - Installation and Operating Instructions

Series PFG Process Filter Gage

The Series PFG Process Filter Gage 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.

MOUNTING

The Series PFG 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 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°. Retighten the plastic

bolts to 20-25 inch pounds of torque.

MAINTENANCE

Upon final installation of the Series PFG Process Filter Gage, no routine

maintenance is required. A periodic check of system calibration is

recommended. The Series PFG is not field serviceable and should be

returned if repair is needed (field 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.
