PVC Instruments NEW!

Filter & Flow Monitors

• For water and corrosive liquids

• Choice of 1" to 3.5" dials

• Popular in water treatment systems

Measure filter or flow performance with our unique instruments with PVC wetted parts. Save thousands of dollars with low-cost solutions. Whether you need local indication, a switch, or a transmitter for remote use, we have those solutions.

Filter Monitors
Monitor filter health with one easy-to-read gauge. A single gauge also simplifies training, installation and maintenance while reducing the errors two pressure gauges present. Our 1002 and 1201 models offer a variety of specifications to met any need.

Specifications - DP

Flow Monitors
Flow efficiency is always an issue. Our PVC variable-area meters relay slight changes in flow rate on a linear scale while withstanding the harshest environments. Unlike rotameters, they are easy to read even with dirty fluids and can be oriented horizontally or vertically. Our 2221FG and 2321FG flow monitors handle the most popular flow rates.

Together, our filter and flow monitors represent simple solutions that don't carry a high cost.
