METHOD FOR RAPID CALIBRATION OF BEVERAGE DISPENSING MACHINE

A rapid sensor calibration technique applied prior to each Sensor 9 measuring a beverage in which water (zero Brix), at same temperature as beverage, is drawn from a Water Supply 3 via Valve 6 and passed over the fixed optic Sensor 9 in order to reference out any sensor temperature changes or beverage temperature changes or sensor surface fouling by the dispensed beverage. This technique of continuous and multiple calibrations, provides an enhanced "beverage dispensing system" calibration beyond that achievable using known calibration methods associated with automatically sensing and controlling beverage quality for soft drinks from a fountain dispenser using, for example, water at a specific temperature to initially calibrate Sensor 9, or using a high quality beverage, from a bottle, for example, at a known Brix level to initially calibrate Sensor 9.
