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.
ALL MX METERS PROVIDE A STANDARD .5% ACCURACY with .03% Repeatability of Flow
- ¼” thru 4” in sizing with .13 GPH to 320+ GPM in Flow Ranges
- Designed for Precise Volumetric Clean Process Fluid Measurement
- No Flow Conditioning – put the meter where you need it
- Large Stock of Meter and Display Inventory including Hazard Classification Meters
- Immediate response to Flow Meter Inquires

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
