Electromagnetic Flow Switch and Flow Meter

• For measuring electrically-conductive liquids, pastes and slurries

• Optional digital display

• No moving parts, maintenance-free




The DWM 1000 electromagnetic flow switch and the DWM 2000 electromagnetic flow meter monitor the flow of electrically-conductive liquids, pastes and slurries.

The DWM 1000 uses an induced voltage converted into a switching signal.

The DWM 2000 uses an induced voltage converted into a 4...20 mA current output that is proportional to the flow velocity.

Measuring principle

As early as 1832, Faraday tried to determine the speed of the current in the Thames by measuring the voltage induced in flowing water by the earth's magnetic field. Electromagnetic flow measurement is based on Faraday's Law of induction. According to this law, a specific voltage is induced in a conductor or conductive medium that moves through a magnetic field. This voltage is proportional to the speed of movement of the medium. On electromagnetic flowmeters, the induced voltage is tapped via two measuring electrodes in conducting contact with the medium. An electronic converter converts the signal into a proportional output signal.
