<p>Portable, container-mounted metering devices for monitoring the dispensing of a predetermined volume of liquid each time the container is moved into a dispensing position. Prior art devices have failed to provide a simple yet complete system for monitoring the number of uses of the container and the volume of liquid dispensed with each use. The present apparatus overcomes these deficiencies by providing an inexpensive, self-contained container-mounted metering device including data storage - capabilities and a motor- operated flow controller arrangement. The apparatus includes a container neck-mounted housing (10) which encloses a flexible outlet conduit (13); a pinch - type flow controller (12); a reverse polarity motor (11) for actuating the flow controller (12); a D.C. power source (20); a pour position sensing, magnetic switch (24); a magnet - operated display device (18); a dispensed quantity variance controller (22); and a logic circuit (100) for controlling the flow controller (12) and display device (18).</p> |
