Macnaught M Series Mechanical Register Flow Meter
Macnaught M Series Mechanical Register Flow Meters are Non-Powered Industrial Grade Mechanical Display totalizing flow devices. Well suited for registering totals in most fluid applications. Designed for clean process fluid, this meter is not for measuring air or liquids laden with solids.
This Macnaught meter class has decades of industrial experience with thousands in service, many operating in perfect condition for over 30 years.
ALL M SERIES MECHANICAL METERS PROVIDE A STANDARD 1% ACCURACY with .03% Repeatability of Flow.
- ½”, 1”, 1,5” and 2” stocked sizes
- Designed for Precise Volumetric Clean Process Fluid Totalizing 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 .1% accuracy
