Series M50 2” Mechanical Meters

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.

The number of gear rotations is a measure of the amount of fluid that has passed through the meter; each rotation is detected by a sensor and the volume is calculated using a conversion factor (K factor).
