Request Information

The Phosphate Ester Flow Meter was designed specifically for monitoring aviation lubricants or fluids with very low specific gravity. The rugged, weather-proof design allows for outdoor installation and wash-downs, unrestricted mounting (horizontal, vertical, and inverted), as well as years of maintenance-free performance. It is available in brass, aluminum, and stainless steel to meet system and fluid requirements and can handle pressures up to 6000 psi.

Applications include:

  • Aviation lubricants such as Skydrol®
  • Fire retardants such as Pydraul®, Fyrquil® and Houghton 900 series

    Choice of Materials
    Select from aluminum, brass or stainless steel to meet system and liquid requirements.

    Unrestricted Mounting
    Allows for horizontal, vertical or inverted installation and does not require straight plumbing on inlet or outlet.

    Multi-Use
    Factory calibrated for phosphate esters, these versatile meters can be used to verify hydraulic power unit outputs, as well as test machinery and tools for proper fluid flow rates.

    Rugged and Reliable
    These meters are constructed with all metal pressure vessels that allow safe & permanent installation.

    High Pressure Operation
    The magnetically coupled follower design allows operation to 6000 PSIG and use with liquids.

    Multiple Ports Available
    Standard selection of NPT, SAE and BSPP ports reduces the amount of adapters required for installation.
