After 40 years of manufacturing in Sydney by Macnaught Pty, a decision to stop production of M-SERIES mechanical display flowmeters in favour of digital models was taken last year. This has now been reversed for 2017 following a review of global distributor feedback and resurgence in customer demand.

Manufacturing of M-SERIES oval gear flowmeters resumes

Oval gear meters are widely recognised as one of the most versatile principles of flow measurement, with their ability to accurately meter a broad range of low to high viscosity fluids without the need for flow conditioning.

Incorporating this unique oval rotor principle into its design has enabled M-SERIES positive displacement flowmeters from Macnaught to offer proven reliability and excellent levels of accuracy and repeatability.

Including a rugged design that minimises the number of wearable and replaceable parts and extends product life, easily fitted and operated mechanical registers, flexibility of installation options; meters can be mounted horizontally or vertically without flow conditioning and they exert minimal pressure drop allowing for economical pump selection or gravity flow applications.

With moving parts inside the meter body limited to a pair of oval gear rotors, maintenance is minimal. Unlike more complicated technologies M-SERIES can be quickly and easily disassembled, serviced and reassembled whilst still in the line without the need for special tools or training.

The M-SERIES model range covers sizes from 0.5 - 4 in. with flowrates from 2 - 1200 LPM and an accuracy reading of +/-0.5%. Offering a choice of construction materials ensures effective use in industrial applications with a wide range of fluid viscosities.
