Macnaught MX Series fuel and oil flow meters are positive displacement oval gear flowmeters that are optimized for fuel and oil measurement applications. They 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 fuel and oil flow meters are the perfect choice for a variety of applications including service and fueling trucks, fuel depots, portable fueling systems, bio-diesel blending and production, lubricant blending and dispensing, hydraulic fluid dispensing and test stands, boiler and generator fuel consumption, fuel consumption for mining, construction, and military vehicles, and bitumen/asphalt production. Flow ranges cover from 0.13 GPH to 317 GPM with accuracy up to ±0.5% (±1.0% for MX06F, MX09F). Temperature range is -40 to 176°F with CE compliance.
