  • pomFPS

    Series FPS provides low voltage signal and visual indication when liquid is present in non-pressurized piping or components. Designed for one-time use; requires simple sensor replacement after the sensor is triggered. In less aggressive chemical applications, the probes may be cleaned and re-used. Suitable for any conductive liquid with a resistance less than 3 Megohm.

    • 24V DC low voltage control wire signals presence of liquid.
    • IP67 DIN Connector with LED indicator and 2M molded cordset included.
    • 1/4" Connection; 1/8" optional for use with Fail-Dry® (Consult Factory).
    • Ideal for leak detection, water sensing, relief tanks, any non-pressurized location where the system operator must be alerted to the unexpected presence of liquid.

    Specifications/Materials of Construction:

    • Sensor available in PVC, CPVC, Natural Polypropylene, and PVDF. Sensing points are 18-8 stainless steel. Rated for maximum 4 amps at 24V DC.

  • pomGLimage2Sketch

    Series GL level indicators utilize a double-wall construction to indicate the level of highly corrosive or ultra-pure liquids compatible with Pyrex glass. They cannot be used with hydrofluoric acid or sodium hydroxide as they will etch the Pyrex cylinder wall. They are available with either PVC, natural polypropylene or PTFE ends in nominal lengths of 1, 2, 3, and 4 feet. FKM seals are standard. Pipe sizes are 1/2" and 3/4" NPT. BSP (British Standard Pipe) threads are also offered. Consult page 4 for pressure and temperature specifications.

  • pomSightGlass

    Plasto-O-Matic Chemical Flow and Level Indicators offer a safe and economical means of indicating flow, clarity, or exact level of extremely corrosive and ultra-pure liquids. Materials Of Construction: A wide choice of plastic indicator end materials is offered to assure maximum chemical compatibility.

    • Ends on Series “GX” indicators are PVC (TYPE 1, GRADE 1 Polyvinyl Chloride) and Polypropylene.
    • Ends on Series “GY” indicators are either PVC, Polypropylene or PTFE.
    • Ends on Series “GYW” indicators are PVC, CPVC (Chlorinated Polyvinyl Chloride),

    Polypropylene, PTFE or Kynar. Standard O-ring seals on Series “GX” indicators are either Buna-N or Viton. On Series “GX”, “GYW” indicators. Viton O-rings are standard. Stainless steel fasteners are standard on all flow indicators. The transparent inner cylinder walls used in the Series “GY”, “GYW” indicators are Pyrex. The transparent outer cylinder walls used in all PLAST-O-MATIC indicators are high impact strength acrylic.
