Provided is an apparatus for dosaging a particulate material. The particulate material includes, at least in operation, a cavity having an inlet opening facing upwardly for receiving the material from an external source, an outlet opening facing downwardly, for disposing therethrough dosages of the material and a dosage feeder located inside the cavity and having at least one dosage recess.

The present disclosure is related to a free flow electronic meter, which is used in measuring the velocity and flow rate of a fluid, particularly in measuring milk yield of sheep, goat, buffalo and cattle during milking. The free flow electronic meter includes a measurement pipe wherein the velocity of the material that passes through it is measured by means of a flow rate measurement sensor. When the milk flows continuously through the measurement pipe, an air passage pipe and/or free air passage pipe prevents vacuum fluctuation that causes udder diseases. This result is reached by preventing a change of the vacuum level during milking due to increased milk flow at teat end by providing extra air passage.
