LIQUID MEASURING DEVICES

摘要

A method and apparatus for measuring flow and/or volume of a liquid preferably milk in which the milk is passed from a passageway through a gap which is long vertically hut 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 in the passageway so that the impedance is changed according to the liquid level and measuring such impedance.
