DWM 1000

The DWM 1000 is a 2-wire electromagnetic flow controller to monitor the flow of conductive liquids, pastes and slurries. The switching point of this insertion-type device is adjustable over a full-scale range of 0.1 …9.9 m/s or 0.3…32.5 ft/s. A welding socket is supplied as standard for welding the DWM 1000 directly onto process pipes (DN50…400 / 2…16"). The long version (DWM 1000 L) is suited for larger pipe diameters or open channels. It comes with either a threaded connection or sliding connection. Both versions are equipped with a safety chain for safe removal of the sensor and with an optional isolation valve. The flow switch is also available with a VARIVENT® connection for hygienic applications.

As an alternative to insertion tubes, an optional spool piece can be used to install the DWM 1000 without welding operation. Amplifier relays are available for a selection of AC and DC voltages. For temporarily or permanently immersed measuring points, the switch can be ordered as IP68 rated version. The DWM 1000 is factory calibrated before delivery.
