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
