Abstract
System and method for controlling the content of a fluid product such as milk. The entire product stream is monitored continuously, and the actual content of the stream is compared with the desired content. A correction signal which varies in accordance with the difference between the actual content and the desired content is provided, and in one disclosed embodiment the content of the product is adjusted in response to the correction signal by an amount which decreases as the content approaches the desired level. In another disclosed embodiment, the butterfat content of both the standardized milk product and an excess cream output are controlled. The correction signals are adapted to control valves which control flow to result in both the standardized milk product and excess cream output having the desired butterfat content.
