ABSTRACT:
An automatic mixture control apparatus includes a micro-computer-based data acquisition and control device which responds in real time to flowmeter and densimeter signals to control water inlet and bulk cement valves so that a cement slurry is produced at the desired rate and density. The data acquisition and control device is programmed to provide means for computing desired positions for the valves and for computing corrections for the positions. A related automatic mixture control method is also disclosed.
