Flow Switch

FW4V-015GM

Flow Switch

● Bidirectional flow switching
● Viscosity stabilised
● Compact design

Characteristics :
Mechanical flow switch, for viscous media, with spring-supported
piston and magnetic triggering of a reed switch.

Handling and operation
Note
● Include straight calming section of 5 x DN in inlet and outlet.
● If the media are dirty, install a filter (use magnetic filter for ferritic components).
● It must be ensured that the values given for voltage, current, and power are not exceeded.
● When switch on, a load must be connected in series.
● The electrical details apply to ohmic loads.
Capacitive, inductive and lamp loads must be operated using a protective circuit.
Adjustment
The setting of the switching points to 1 l/min is carried out in the
factory.
