Calorimetric flow switch FS 11 is produce with 2 × status output (depending on flow velocity).

It is a device that monitors the flow of fluid based on calorimetry principle. If the flow rate drops below a limit set by user, the status output is changed. The flow rate is displayed by ten LEDs and it is possible to select a boundary for contact making/breaking in the same graduation. The measuring cycle takes from 4 sec to 8 sec with the recommended measurement range 4 ÷ 150 cm/sec. In case of an empty pipeline, the sensor behaves in the same way as with zero flow.

Meter states displayed

The flow switch point on LED scale can be implemented using two colours (red LED or amber LED), indicating at the same time which contact is normally closed or normally, open. In case of FS15, the temperature switch point is indicated by the LED located between the control push buttons. If the temperature of media is above/below the set-point, the LED is red, indicating that PIN2 is open at the same time (the sensor supplied as standard is configured open at a temperature above the set limit with the LED turned ON). If the logic of the normally open/normally closed point is changed by the user, the logic of both outputs is changed at the same time (applicable to FS 11 and FS15 versions).

The flow switch has two flush-type control buttons, making it possible:

  • the switching point/points for flow velocity (temperature in some case)
  • to change the logic of the N.O./N.C. output
  • to calibrate the minimum and maximum flow values of the monitoring device
  • to reset the original parameters from factory
