Description

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 .5 LPH to 2500 LPM 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

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 assistance. 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.
