Abstract
Abstract A liquid is delivered to a channel. The channel contains a baffle extending thereacross at a position below the top surface of the liquid but spaced from the bottom of the channel. By varying the submerged position of the baffle in the liquid with respect to the bottom of the channel, the rate of flow of the liquid through the channel is controlled. A prescribed quantity of liquid may be delivered from the channel by positioning the baffle at a prescribed, submerged position within the liquid flowing through the channel.
