Abstract
A dispensing and pour control system for a regulated beverage having a metering system that provides a discharge in a controlled and metered manner. A sensor system uses a Line Control Board (LCB) that detects a piston location inside a metering conduit. A plurality of magnetic sensors is positioned at equal intervals and in the same plane collinear with the movement of a magnetic piston within the metering mechanism conduit. The piston position is detected by obtaining a set of momentary readings of the magnetic sensors and estimating a location of the piston by interpolation of the piston position as an anticipate location between sensors that are adjacent and showing readings of opposing signs.
