Abstract
A method and apparatus for measuring liquid flow, particularly milk, includes directing the liquid to flow through one or more flow channels, while exposing the liquid to electromagnetic radiation; measuring the transparency to electromagnetic radiation of the liquid flowing through the flow channel; and measuring the momentary attenuation of electromagnetic radiation by the liquid flowing through the flow channels, to determine the momentary volume of the liquid flowing through the flow channel. The momentary velocity of the liquid flowing through the flow channels is also determined, thereby permitting a determination of the momentary flow rate of the liquid flowing through the flow channels.
