A method and apparatus for measuring flow and/or volume of a liquid preferably milk in which the milk is passed from a passageway (3,56) through a gap (5,46) which is long vertically but narrow in width so that a pool is formed in the passageway, the height of milk in the pool being a measure of the rate of flow of the milk. The levels maintained over predetermined intervals of time are integrated to give volume measurements. Measurements of levels are made by providing a resistor (8,32) in the passageway (3,56) so that the impedance is changed according to the liquid level and measuring such impedance.
