IFM SM Series
The sensor display includes a 4-digit numeric display with eight integrated LEDs that together indicate the flow rate (gal/min or l/min), total volume (gallons or liters), and temperature (°F or °C) of all conductive media. Simple pushbutton programming quickly establishes application parameters and the flow meter can be setup to provide a switching output, analog output and pulsed output.
The sensor offers high accuracy with a response time of less than 0.15 seconds and a repeatability of ±0.2%. 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.
