For liquid flow monitoring where cost, simple switching and robust mechanics matter, this family gives you a practical way to detect flow in water applications. The spring-supported piston is magnetically coupled to a reed switch, giving a clear mechanical switching principle for liquid media.
The compact brass and POM construction is designed for liquid media and specified as dirt-insensitive, helping it cope with less-than-perfect water conditions when the recommended filter is used. Sizes cover DN 8 to DN 25 with G 1/4 to G 1 internal threads, switching ranges from 1 to 11 l/min H2O and a pressure rating of PN 100 bar.
Commissioning stays straightforward: the switching head can be shifted into position after loosening one screw, then fixed again. With max. 230 V AC, 0.5 A and 50 VA switching data, plus ingress protection rating IP67, the unit is well suited to dependable flow indication in liquid circuits.
The flow switch uses a spring-supported piston with magnetic actuation of a reed switch for liquid media.
The family covers nominal sizes DN 8 to DN 25 with internal threads from G 1/4 to G 1. Further connection types are possible on request.
The switching head is moved after loosening a screw and fixed again once the desired position is reached.
The standard configuration is specified for water. Switching values for oil and versions for aggressive media are available on request.
A straight calming section of 5 x DN is specified in the inlet and outlet. Filters are recommended for contaminated media.
