Method of detecting a flow, detection device, automatic milking device and computer programThe present invention provides a method and a device (1) for monitoring a flow of milk (8) in a milk line (2) which is connected to a teat cup (3) and which has an aeration opening (5), like in a milking device. For this purpose, the milk filling level is monitored in a measuring section (7) of the line. If the variation therein is too little, the absence of a flow, or at least an inadequate flow, is established. If, additionally, a (sufficient) filling level is detected, it can be concluded that there is an obstructed aeration opening (5).
