Abstract
A dairy chemical dispensing system for supplying an amount of at least one chemical to a utilization point in a dairy wash system, comprising: (a) an operator input controller for receiving operator input comprising input of a given amount of chemical to be supplied to the utilization point, and providing a signal corresponding to the operator input; and (b) a chemical dispenser in operative contact with the operator input controller, comprising a chemical source conduit, a pump connected to the chemical source conduit and to a chemical output conduit for supplying the chemical at a predetermined flow rate to the utilization point, a flow sensor connected to the output conduit for measuring an actual flow rate of the chemical through the output conduit, and a data processor electrically coupled to the pump and the flow sensor, where the data processor PA1 (1) receives the signal from the operator input controller, and based on that signal, determines a pump activation time necessary to supply the given amount of chemical, PA1 (2) periodically monitors the actual flow rate by comparing the actual flow rate to the predetermined flow rate in repeated flow measurement cycles, and PA1 (…
