DP04 Paddle-type flow switch with shortenable paddle

The model DP04 flow switches operate according to the pad­dle principle. The flowing liquid pushes against the surface area of a paddle mounted at the end of a pivoting arm. The dynamic pressure against the plate deflects the arm. This motion causes a permanent magnet attached on the other end of the arm to switch an adjustable reed contact located outside the liquid being monitored. By moving the reed con­tact, different switching points can be set.

Two repulsive magnets generate the restoring force. This results in better long-term stability and higher tolerance to pressure peaks.

The possibility of installing the flowmeter directly in the pipe­line and shortening the paddle individually results in very flexi­ble areas of application.

The DP04 paddle flow switch is suitable for monitoring the switching point of low-viscosity liquids.

Typical fields of application:

– Cooling systems
– Heating systems
– Welding systems
– Laser cooling systems

Due to the paddle principle the device is really intensitive to dirt.
