Download PDFFlow switch suitable for any pipe with a size of DN 20 ... 200 . No maintenance required. You can manually set whether the switch should switch on or off. It controls the flow in hydraulic systems - in heating systems, with cooling devices and heat pumps.
The flow of fluid through the pipe will cause the vane system (1) of the switch to move. At the end of the vane system there is a permanent magnet (2), which approaches the reed relay (3) as the system moves. The return force is generated by a second magnet (4) with opposite polarity. Depending on the selected type, the contact closes or opens. As soon as the fluid flow stops, the vane returns to its original position and the relay either opens or closes again.
The switch is mounted in a 1/2 "T-fitting. In front of and behind the place where the switch is mounted, there must be a calming section 10 times the nominal pipe flow. The arrow on the switch body should point in the flow direction during installation.
It is suitable for all liquid media except ammonia.
