Abstract:
An optical liquid height determination system of the present embodiments includes light sensors capturing different amounts of light, based on level of liquid in the tank that blocks or limits light to particular sensors. The tank is enclosed in a container with a light source and the light sensors are installed on walls of the container. Light emitted by the light source is transmitted to the light sensors by passing through the liquid product, scattered, diffused, diffracted or reflected by the dairy product, through the tank walls which may be transparent or translucent, or from other surfaces in the container within which the tank is enclosed by. The set of electrical signals received from all the light sensors are compared against sets of calibrated signals corresponding to known liquid levels in the tank. The known height corresponding to the nearest set of calibrated signals is determined as the measured liquid height in the tank.

Claim (Index 1):
A method for approximating liquid height in a tank in a container using at least two light sensors arranged along a vertical direction of the container proximate the tank and prestored sets of calibrated signal values of the light sensors corresponding to known discrete levels of the liquid height, comprising:\n activating a light source within the container; generating an electrical signal value from each of the at least two light sensors in response to light sensed by each of the at least two light sensors to form a set of measured electrical signal values; accessing the prestored sets of calibrated signal values from a memory, where each prestored set of calibrated signal values includes a calibrated signal value for each of the at least two light sensors that corresponds to one discrete level of the liquid height; executing mathematical calculations on the set of measured electrical signal values and the prestored sets of calibrated signal values to determine one prestored set of calibrated values nearest to the set of measured electrical signal values; and outputting a discrete level of the liquid height corresponding to the one prestored set of calibrated values as the approximate liquid height in the tank on a display.
