Isolation Rings & Gauging Products
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.
Pressure is monitored by the gauge or the switch, which is completely
isolated from the process flow.
