The Revolutionary MX Series

The new generation of Macnaught Flow Meters, the MX series, is the revolutionary result of over 47 years' experience applying Positive Displacement Flow Metering Technology to a variety of industries; all of which insist upon durability, reliability and excellence in performance.

Incorporating Oval Gear technology, the MX series is a range of Positive Displacement Flowmeters specifically designed to withstand the rigours of the typical industrial environment, without compromising overall performance.

Ranging from sizes ¼″ – 4″, and suitable for flow rates from 0.5 lph to 1200 lpm, the MX SERIES offers a complete range of 316 Stainless Steel and anodised aluminium flowmeters to suit most any industrial application.

A key feature of the MX series is the revolutionary new M-LOCK mounting system, designed for the quick and easy fitting of a Pulser or local Display module to the flowmeter.

The unique bayonet style cam is common to all of the modules, enabling the customer to fit any one of the 6 output options to anyone of the MX Flowmeter Models.

Simply a ¼ turn locks the module into place, and it is immediately ready for service.
