ifm efector SM4000 inductive flow sensor

Click2Contact

The ifm efector SM4000 flow sensor is based on Faraday’s principle of induction. The conductive medium flowing through a pipe in a magnetic field generates a voltage which is proportional to the flow velocity or flow rate. This voltage is detected via electrodes and converted in the evaluation electronics.

Analog, binary and pulse outputs offer various possibilities to process the measured data. In addition to flow rate, temperature and totalised values are also available. Due to the flexible programming by means of push-buttons, the flow sensor can be adapted to different conditions. The sensor is mounted via an adapter and is available with an EPDM O-ring for drinking water applications. Measurement values are presented using a 4-digit alphanumeric LED display.

The SM4000 is suitable for conductive liquids with a flow rate of 5–3000 mL/min with a conductivity down to 20 µS/cm and viscosity less than 70 mm²/s (70 cSt) at 40°C.
