ISO-Ring® Gauge Isolation Ring
Brand: OPW Engineered SystemsOPW'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.
Features- Gauge or Switch is In Contact Only with Captive Liquid and Never Directly with the Process Liquid.
- Isolating the Gauge or Switch from Solids in Process Flow Results in Accurate Readings.
- Gauge or Switch can be Removed for Calibration, Repair, or Replacement - without Interrupting Process Flow.
- Unique Flexible Cylinder Prevents Plugging, which Means Pressure Readings are Reliable and Accurate.
- Integral Design Eliminates Accidental Breakage.
- Adaptable to a Variety Of Process Conditions and Applications.
- Will not Clog - which is not True of Diaphragm Seals
