Product specification

The flow switch is fitted in its flow room with a bounce plate attached to one end of a balance arm placed in the flow room and bearing a barium-ferrite magnet on the other end. Effects of friction are almost prevented. The magnet operates a reed contact in a switching tube placed outside the flow room. Depending on the setting of this switching tube, the reed contact operates as working current or closed-circuit current switch.

The flow switches are used for monitoring aggressive and non-aggressive media. The maximum operating pressures amount to 16 bar for the brass version and 25 bar for the stainless steel version, both at maximum operating temperatures of +110 °C. The flow switches are safe in operation at small pressure drops in the device and unsusceptible to soiled media and scale formation in the device interior.
