FLOW SWITCH 10/11/15/20 BASED ON THE CALORIMETRIC PRINCIPLE
(Made in four versions depending on flow velocity)
FS 11 – 2× status output (depending on flow velocity)
FS 15 – 2× status output (1× depending on flow velocity and 1× on temperature)
FS 20 – 1× status output and 1× current output (depending on flow velocity)

If the flow rate drops below the user specified limit, the status output will be changed.
The flow rate is indicated by ten LEDs within the measurement range and you can select the boundary for making/breaking the contact in the same graduation.
The measuring cycle takes from 4sec to 8sec with recommended measurement range 4 ÷ 150 cm/sec.
If the piping is empty, the sensor behaves identically as in the case of zero flow rate.
 
SENSOR CONTROLST
he flow switch contains two flush-buttons by which means it is possible to set

Switching point/points for flow velocity (or temperature in some case)
To change the logics of the making/breaking output
To calibrate minimum and maximum flow rate for the sensor
To reset default parameters from the manufacturer
