  • A push-button:
    1. Press shortly: Calibrate the node. Make sure there is beer in the detector. After the LED turned green you can restart tapping. When the red LED is lit up, the node is already or can not be calibrated.
    2. Press more than 1 second: Clean mode. The contacts are now open; it's possible to clean the pipes via the tap valve. The Fob-detector will not react on an empty barrel. The red and green LED flash.

Installing the sensor



  • The way the sensor is installed is very important, it has to be in a VERTICAL position.
  • when a beerpump is not used, it is possible that small bubbles of gas leave the tank and enter the beerline, these bubbles can become a lager concentration of bubbles. We have to make sure that this concentration is BEHIND the foam detector. (see RIGHT drawing above)
  • LEFT = CORRECT tab RIGHT=WRONG
  • avoid folding of the beerlines
  • The line between the sensor and the 3-way faucet needs to be 1.5 meters minimal
