Compact pipework leaves little room for unnecessary length, especially when flow still needs to be monitored clearly. This mechanical flow switch combines a short installation length with precise, stepless switching value adjustment and repeatable operation in liquid lines.
Flow lifts a magnet-equipped piston from the valve seat against spring force, triggering a hermetically separated Reed switch. Stainless steel wetted materials, H2O switching ranges from 1-200 l/min and recommended Qmax. values up to 290 l/min make the device a practical choice for water applications with G 1/2 to G 2 internal thread connections. PN 100 bar pressure resistance supports use in robust pipe systems.
Standard installation is based on horizontal flow, with the switching head not recommended in a downward position. Straight calming sections of 5 x DN in the inlet and outlet support stable switching behavior. Optional ingress protection (IP65), temperature indication, temperature monitoring and oil switching ranges allow the configuration to be adapted to the application.
Flow lifts a magnet-equipped piston against spring force and actuates a hermetically separated Reed switch.
The product family uses G internal threads from G 1/2 to G 2 for nominal widths from DN 15 to DN 50.
H2O switching ranges are selected by version and apply to horizontal flow with decreasing flow rate.
The standard connection uses a DIN 43650-A / ISO 4400 plug and a changeover Reed switch.
Horizontal flow is the standard arrangement. Other installation positions are possible, but they affect the switching point or switching range.
The switching point is adjusted by loosening the switch head fixing screw and rotating the switch head.
Straight calming sections of 5 x DN are required in the inlet and outlet. Filters are recommended for contaminated media.
Options include special connectors, signal lamps, ingress protection (IP65), temperature indication, temperature monitoring and a metal cover.
