ISO-Ring® Data Sheet
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.
