ISO-Ring® Gauge Isolation Ring

OPW's patented Gauge Isolation Ring, called ISO-Ring®, is designed to isolate gauges or pressure switches from solids in process flow and to ensure accurate pressure readings.

Why ISO-Ring?

Clogging or fouling typically associated with diaphragm seals used in viscous fluid applications result in erroneous pressure readings.

This is never a problem with the OPW ISO-Ring®.

ISO-Ring® utilizes a specially designed flush-mounted flexible inner cylinder, behind which is a clean, captive liquid.

As process liquid flows through the pipe, it exerts pressure through the flexible cylinder to the captive liquid.

There’s a common refrain reverberating throughout the industrial world these days, and its message is unmistakably clear: Out with the old diaphragm seal. In with the OPW’s ISO-Ring®.

Indeed, for the steady and growing number of companies embracing and implementing this simple call-to-action, something powerfully refreshing and highly reassuring is happening as process liquid flows through their pipes: Process flow is smooth and uninterrupted; pressure readings are consistently reliable and accurate.

Thanks to OPW's advanced, patented Gauge Isolation Ring, gone are the days when solids from the process flow plug the pressure-sensing mechanism or clog the access port on the diaphragm seal.
