Flow Measurement and Monitoring DP01 Paddle-Type Flow Switch • for liquids • long-term stable switching points by counter magnet technology • with or without T-fitting for piping from 1/4“ to 6“ • design in brass, stainless steel and with PVC T-fitting • upper part detachably connected with T-piece, thus cleaning and exchange fast possible • switching range: 2,1...83 l/min water • available with reed contact or microswitch • instant response • switching function depends only on flow, not on pressure and temperature of fluid Typical application: The model DP01 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 DP01 paddle flow switch is suitable for monitoring the switching point of low-viscosity liquids.
