Inspired by the DuoFiller we designed our own dual can filler with automatic level sensors and purging.

The level sensors is based on two digital pressure sensors, gas valves are just ordinary electromagnetic valves and the beer valves are the same pinch servo valves as we use in the brewery. Everything is controlled by a Raspberry Pi and we made an app to control filling level and purge times individually per beer line.

One nice feature is that we can disconnect the hoses and dismount the parts that gets messy and rinse them off.
