Flow Measurement & Control


Inductive flow measurement

November 2008 Flow Measurement & Control

ifm electronic has introduced the SM Series Magmeter, a magnetic inductive flowmeter designed to detect the flow rate of conductive fluids in pipes of known diameter – up to a maximum of 27 litres per minute. Operation is based upon Faraday’s Law of electromagnetic induction, which states the voltage induced across any conductor as it moves at right angles through a magnetic field is proportional to the velocity of that conductor.

Magmeter has a four-digit numeric display with eight integrated LEDs that together indicate the flow rate, total volume, and temperature of all conductive media. Simple pushbutton programming quickly establishes application parameters.

The meters can be setup to provide a switching output, analog output and pulsed output with high accuracy and response times of less than 150 ms. Electrical connection is made through an M12 connector.

Typical applications include flow and temperature monitoring through heat exchangers, monitoring cooling water on welding machines, batching applications, totalised flow of process water and pump run dry protection.
