Abstract
The batch control system is used in a batching system for controlling the batching of a fluid material from one container to another container through a conduit having a pump coupled therein, a flowmeter coupled therein and a valve coupled therein. The batch control system includes a microprocessor; a keypad coupled to said microprocessor; a battery backed non-volatile memory coupled to the microprocessor; a serial port in the microprocessor; an alpha-numeric display coupled to the microprocessor; relay control outputs coupled to said microprocessor and to relays for controlling energization of the pump and the valve, respectively; at least one input coupled to the microprocessor for receiving count pulses from the flowmeter; and, outputs for supply data to a station remote from the location of the batch control system, such as a manager's office or a station at the location of one of the containers.
