Abstract
A control system (10) is provided for maintaining a constant fluid level in a mixing container of a delivery and metering device. Structure (12) is provided for monitoring the fluid level in the mixing container and for generating a level signal (14) representing the fluid level present in the mixing container. Structure (18) is further provided for establishing a desired amount of fluid entering the mixing container and for generating a first control signal (20). Structure (22) is provided for establishing a desired amount of fluid discharged from the mixing container and for generating a second control signal (24). Measuring devices (30, 34) are utilized for measuring the amount of fluid discharged from the mixing container and for generating a discharge signal (36) representing the amount of fluid discharged from the mixing container. Circuitry (16) is provided for receiving the control signals (20, 24) and the level signal (14) for generating pump signals (40, 42) applied to inlet and discharge port pumps in response to the discharge signal (36).
