Macnaught resumes production of M-Series mechanical flowmeters to answer renewed demand

Australian fluid measurement and handling equipment designer Macnaught has restarted the manufacture of the M-Series mechanical display flowmeters after distributor feedback and resurgence of customer demand.

The company put a stop to producing the mechanical meters in 2016, replacing the product in its portfolio with digital models.

Oval gear meters are popularly held as one of the most versatile flow measurement devices, as they are able to accurately meter fluids over a wide viscosity range 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 high levels of accuracy and repeatability, the company said.

The meters include a rugged design that minimises the number of wearable and replaceable parts and extends product life, easily fitted and operated mechanical registers, and flexibility of installation options

They 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 meters 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” with flowrates from 2-1200l/min 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.
