ISO-Ring Gauge Isolation Ring

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/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).
