Abstract:
A system for feeding a product into a process stream, the system comprising:first sensing means in communication with the process stream capable of detecting a change in frequency in the process stream and producing a first signal indicative of the change;second sensing means in communication with the process stream capable of detecting a change in frequency in the process stream and producing a second signal indicative of the change;processing means receiving the first signal from the first sensing means and capable of producing a third signal indicative of a quantity of mass on the first sensing means in the process stream, the processing means also receiving the second signal from the second sensing means and capable of comparing the first signal and the second signal and generating a fourth signal indicative of a difference in mass quantities on the first and second sensing means; andfeeding means operatively connected to the processing means and capable of receiving the third and fourth signals from the processing means wherein the feeding means initially feeds the product into the process stream upon receipt of the third signal and controls the feed of the product based on the fourth signal.
