Flowswitch DW-R – Very versatile! Very safe to use!
The DW-R device type has proven itself to be a simple, reliable and cost-effective solution for the monitoring of flows in pipelines. Special versions with regard to materials, switching behavior and/or switching points, connection variants can be supplied on request. Contact us.
Problem-free measuring method
The DW-R model series functions very reliably in accordance with the dynamic pressure principle. If the flowing medium meets the circular pressure plate at the end of the pendulum, the pendulum system is moved. The pendulum system is supported by a pre-stressed leaf spring so that it can be swiveled without friction. A permanentmagnet at the end of the pendulum system operates a movable reed contract (protective gas contact). This switching unit is located outside the medium.
• divided structure, upper part and pendulum system fixed to the pipe part, ensuring that cleaning can be done easily and quickly – without adjustment
• simple exchangeability of the entire pendulum system
• Pendulum system available as a standard feature in stainless steel
• Function independent of pressure
• low pressure loss
• simple, reliable and costeffective flow switch
• insensitive to polluted media and calcification (except magnetic particles)
