Macnaught MX Series solvent meters are positive displacement oval gear flowmeters that are optimized for Solvent and High Temperature fuel and oil measurement applications.

Macnaught solvent meters are constructed utilizing a robust cast aluminum body suitable for use in the harshest environments. Their 316SS and aluminum rotors provide exceptionally low pressure drop and can even be used in gravity fed applications as well as high temperature fuel & oil measurement. The 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 solvent flow meters are the perfect choice for a variety of applications including:

  • Industrial paints and coatings
  • Ink blending & dispensing
  • Sealants & adhesives manufacturing
  • Agrochemical production
  • Cleaning chemical manufacturing & production
  • High Temperature fuel oil measurement for industrial and marine applications
