Description

The 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.

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. Pressure is monitored by the gauge or the switch, which is completely isolated from the process flow.

Features and Benefits

  • 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).
