FLOW SWITCH 10/11/15/20

(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 CONTROLS

The 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

ADAPTER BLOCK

If the flow rate of medium is to be monitored in a pipe smaller than DN25 (or the flow velocity is below the sensor range for the given pipe diameter), it is advantageous to use an adapter block with the corresponding flow velocity and thereby ensure proper functioning and maintain the installation conditions. The adapters are designed for the short version of 65mm sensor with the use of direct neck with G½“ pipe thread.
