WHAT IS AN ISO-RING?

  • An ISO-RING (also known as a pressure instrument protector, a gauge isolator, and a pressure sensor) is a device which protects pressure measurement instrumentation from many potentially damaging applications.

    WHY PROTECT INSTRUMENTATION?

    The goal of the ISO-Ring is simple:
    ASSURE ACCURATE PRESSURE MEASUREMENT!!!

    No matter how sophisticated the instrumentation, it is useless if it becomes damaged, or is in any way unable to measure pressure.

    PROTECT INSTRUMENTATION FROM WHAT?

    Many applications in which pressure is measured involve slurries (liquid containing solid particles), viscous liquids, or any liquid which can accumulate in the entrance to the instrumentation, preventing the process fluid from reaching the instrumentations pressure sensing element.

    Other applications involve substances which are corrosive, or otherwise harmful to the instrumentation itself

    THE SOLUTION TO THESE PROBLEMS IS SIMPLE PROTECT INSTRUMENTATION WITH THE ISO-RING!!

    HOW DOES THE ISO-RING PROTECT INSTRUMENTATION?

    An ISO-Ring consists of the following essential parts.

      1) BODY
      2) ASSEMBLY FLANGES
      3) FLEXIBLE CYLINDER
      4) CAPTIVE SENSING LIQUID
      5) INSTRUMENT REMOVAL DEVICE (IRD)

    The ISO-Ring consists of a sensing liquid "sandwiched" between a metal body and a flexible cylinder.

    The process liquid, as it flows through the ISO-RING, exerts pressure against the 360° flexible cylinder.

    The pressure is then transmitted by the sensing liquid through a port in the body, to the instrumentation.

    THE RESULT: A clean, compatible liquid activated the sensing mechanism of the instrumentation.

    The ISO-Ring is simply mounted between two (2) process piping flanges.*

    * CUSTOMERS MUST SUPPLY GASKETS NEEDED BETWEEN ISO-RING AND PROCESS FLANGES
