       better for the environment,
       are easier to pack and
       transport  so  we  gave
       ourselves a challenge to
       design and build a system
       where  we  could  filter,
       carbonate and can beer, on a
       relatively small budget.”
         Their  first  canning
       machine relied on optical
       sensors to detect foam in the
       can and they quickly realised
       this was not an effective or
       robust enough option and fill
       levels could not be relied
       upon. Also the sensor
       counting the cans was a
       photoelectric optical eye
       sensor and due to its shiny,
       reflective  nature  the
       aluminium would give false
       or multiple readings.
         These  issues  were
       resolved once the Baumer
       sensors were installed with
       the LBFS sensor providing
       accurate and repeatable fill
       levels regardless of the
       presence of foam, meaning that the cans did not   though we are a small microbrewer. They gave us
