 The Macnaught M-Series Flow Meter class consists of Macnaught's M1 Square Body Digital, MH High Pressure, and CR Chemical Resistant Flow Meter products.

The M1 square body is designed for the smallest flow meter footprint applications.  Macnaught's F006, F009, M006, and M009 meters are FNPT, 800 PSI, Square Body Flow Meters with Reed / Hall Pulse Output.

The MH High-Pressure Meters and designed for high pressure applications.  Macnaught offers Stainless Steel Meters in 8,000 PSI Options and a 1/2 Stainless Steel meter in 3,000 PSI options

The CR Chemical Resistant Meters and designed for aggressive chemical applications. 

  • CR006, CR009 FNPT 75 PSI rated Meters in PPS Body / PPS Rotor / Hastelloy Shaft and FFKM Body Seal
  • CR025 1 FNPT  150 PSI rated Meters in PPS Body / PPS Rotor / Hastelloy Shaft and FFKM Body Seal


M-Series Digital Flow Meters Principle of Operation:

  • The measuring element of an oval gear meter consists of two high-precision splined oval-shaped gears (Rotors).
  • The gears are driven by the flow of the media and mesh together. In the presence of flow, exact known defined volumes of fluid are swept through the meter per each rotor rotation.
  • As flow increases, so does the rotational speed of the Rotors.
  • The number of revolutions is a precise highly accurate measure of the fluid that has passed through the meter. Regardless of viscosity, pressure, or temperature.
  • Each active Rotor rotation creates a pulse and is detected by a sensor. Each meter is individually calibrated per ISO 17025 standards to .5% accuracy
