Flow Measurement Mcmenon

Accurate, and reliable flow solution with negligible pressure loss….

The Electromagnetic Flowmeter (EMF) or Mag flow meter are a tried and tested technology used in many industries worldwide.

Anywhere the measurement of a conductive fluid is required, they are among the most popular choice of technology owing to their low cost and reliability.

From clean potable water through to sludges and slurries and even molten metals, EMFs can deliver a stable and accurate measurement.

They require only short lengths of upstream straight lengths of pipe to ensure accuracy and are full bore devices with no instructions into the flow and therefore no appreciable pressure loss.


The EMFs come with many features and options the end user can select to meet their needs.

This includes several communications outputs like simple 4-20 mA channels, HART, Modbus RTU/TCP, GSM/GPRS and relay outputs from alarms.

This functionality helps users build a specific solution for their own application.

Sizing and selection is simplified by use of McMenon Solve, the ultimate tool for DP flowmeter sizing and more, used on-line
