Macnaught MX Overview
Macnaught MX Oval Gear Flow Meters are Industrial Grade Positive Displacement Flow Meter devices. Our MX Meters provide true volumetric measurement of liquid thru the meter – not of scale, but actual flow measurement.
MX Meter bodies are machined of solid billet, our Rotor shafts are hardened alloy and our Rotor design is unmatched for accuracy and reliability. Our MX PD Meters are for clean fluids, only – no gases or solids-laden liquids.

Principle of Operation
Principle of Operation
The measuring element of an oval gear meter consists of two high-precision splined oval-shaped gears (Rotors).
The gears are driven by the flow of the media and “mesh” together. In the presence of flow, exact known defined volumes of fluid are swept through the meter per each rotor rotation.
As flow increases, so does the rotational speed of the Rotors.
The number of revolutions is a precise highly accurate measure of the fluid that has passed through the meter. Regardless of viscosity, pressure, or temperature.
Each “active” Rotor rotation creates a pulse and is detected by a sensor. Each meter is individually calibrated per ISO 17025 standards to .5% accuracy

Oval gear Flow meter contains operating and maintenance
instructions for the MX-Series Flow Meters. This
covers port sizes from 1/4” to 4”.
Refer to separate instruction manual for information
on operating modes and features of LCD displays.
Contact local representative or distributor for further

This Flow Meter has incorporated the oval gear
principle into its design. Exceptional repeatability and
high accuracy over a wide range of fluid viscosities
and flow rates are features of the oval gear meter design.
With a low pressure drop and high pressure rating
oval gear flow meters are suitable for both gravity
and (in-line) pump applications.
Operating Principle of Oval Gear Flow Meter
Fluid passing through the meter causes the rotors to turn, as shown below. One of the rotors (the active rotor) is fitted with magnets. The passing of the magnets are picked up by the electronic sensor. The excitation of this switch provides a ‘Raw Pulse Output’ which relates to the K-Factor. (e.g. KF 36 = 36 pulses per litre of fluid passed) This Pulse Output Signal can either be fed to an external receiving element (e.g. Data Logger or PLC) or alternatively to an LC Display which conditions the Pulse signal to display volume of fluid passed. (e.g. Display 1 Litre per for every 36 pulses received).Benefits of Oval Gear Flow Meters
- High Accuracy & Repeatability – Delivers precise flow measurement with exceptional repeatability, even across varying fluid viscosities.
- Wide Range of Fluid Compatibility – Suitable for measuring various fluids, including oils, fuels, chemicals, and viscous liquids.
- Low Pressure Drop – Ensures minimal impact on the flow system, making it ideal for gravity-fed and pump applications.
- Durable & Long-Lasting – Designed with robust materials for superior wear resistance and long-term reliability in industrial environments.
