ABSTRACT:
A portable apparatus for controlling the production of a mixture of a fluid and a plurality of additives utilizes a unified control panel having all of the necessary controls compactly contained in a single housing for providing both automatic and manual control of each of the additive channels through which the additives are mixed with the primary fluid. The control of each additive channel is achieved through a software controlled algorithm by which errors are only incrementally, rather than totally, applied to prior drive signals at any one time.
