1 minute, 40 seconds Read

Macnaught MX09 Series Model ¼ Digital Flow Meters are suitable for flows between 4-132 GPH. The ¼” Digital Flow Meters have an accuracy of +/- 0.5% and provides exceptional levels of reliability and durability.

Macnaught’s Positive Displacement Flow Meters are suitable for a wide range of industrial applications including fuel and oil distribution, corrosive chemical, solvent measurement and high pressure applications to name a few. Macnaught offers Positive Displacement Flow Meters featuring Oval Gear technology.

The measuring principle includes two high-precision toothed oval gears, which are driven by the flow of the medium and mesh with each other: in presence of a flow, defined volumes of fluid are transported through the meter for each rotation of oval gears pair. As the flow rate increases, so does the rotational speed of the rotors.
