Macnaught MX Series industrial meters are positive displacement oval gear flowmeters that are designed to cover a broad range of industrial fluid measurement applications. With versions covering high temperature, high pressure, as well as hazardous locations, there is a Macnaught Industrial flowmeter to fit virtually any industrial liquid measurement requirement.

Macnaught industrial meters are constructed utilizing a robust cast aluminum body suitable for use in the harshest environments. Their bearing-less PTFE/PPS rotors provide exceptionally low pressure drop and can even be used in gravity fed applications. This unique rotor design ensures minimal wear resulting in many years of reliable service. This approach has proven over time to provide consistently accurate flow measurement that is not affected by variations in temperature, viscosity, or pressure.

Another benefit of Macnaught's unique rotor design is simplicity of repair. With only 2 moving parts, the meters are simple to repair, require minimal repair parts stock, and can even be repaired inline, resulting in less downtime.

Oval Gear flowmeters are ideally suited to applications requiring accurate dispense quantities. Measurement of very low flow rates, pulsating flow, small batch sizes, viscous products, and non-conductive liquids are all ideal uses for oval gear meters. Because these meters don't require flow conditioning, no straight piping runs are required, so they can be used in installations where space is limited without effecting performance.

With a range of display, output and process connection options, Macnaught MX Series industrial flow meters are the perfect choice for a variety of applications including:

  • Chemical batching
  • Additive injection
  • Hydraulic test stands
  • High temperature chemical processes
  • High pressure chemical processes
  • Food and beverage batch processes
  • Ethanol blending and production
  • Pulp and paper
