IFM magnetic meters accept higher flow rates

IFM Electronic is offering larger versions of the SM Series Magmeter.

The magnetic inductive flow meter, which is designed to reliably detect the flow rate of conductive media, will now cope with to up 50l/m in the SM7 series or 100l/m in the SM8 variant.

The SM Magmeter's stainless-steel, mechanically-robust design is mounted in-line, providing a compact, low-profile installation for process control.

The sensor display includes a four-digit numeric display with eight integrated LEDs that together indicate the flow rate, total volume and temperature of all conductive media.

Pushbutton programming establishes application parameters and the flow meter can be set up to provide a switching output, analogue output and pulsed output.

The basic unit is calibrated in SI units, while for those exporting to USA, for example, further devices calibrated in gallon or Fahrenheit can be supplied.

The sensor offers high accuracy with a response time of less than 0.15s and a repeatability of +/-0.2 per cent.

Electrical connection is made through an M12 connector.

The principle of operation is based upon Faraday's Law of electromagnetic induction that detects the flow velocity of an electronically conducting fluid through a defined pipe diameter.

Faraday's Law states that the voltage induced across any conductor as it moves at right angles through a magnetic field is proportional to the velocity of that conductor.

Typical applications include: flow and temperature monitoring through heat exchangers; monitoring cooling water on welding machines; batching applications; totalise flow of process water; pump run dry protection and guarding welding equipment against loss of cooling water.
