OPW-Iso-Ring Pressure Instrument Protectors
OPW Engineered Systems’ patented Iso-Ring technology is designed to isolate gauges or pressure switches from solids in process flow and assure accurate pressure readings. Clogging or fouling typically associated with diaphragm seals used in viscous fluid applications is never a problem. That’s because Iso-Ring has a 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. The gauge or switches sensing mechanism monitors the pressure. In other words, the gauge or switch is completely isolated from the flow.
