Abstract
A device for measuring the volume of flow in a liquid conveying apparatus wherein drops of the liquid are formed and directed into a length of measurement tubing having a known internal diameter. As the drop is passed through the measurement tubing its length is determined by a combined optoelectronic mechanism including drop length sensors. The drop forming portion and measurement tubing can be manufactured from inexpensive resinous materials making these portions disposable and particularly adaptable to intravenous administration.
