Abstract
A load cell and system for detecting the quantity of liquid carbon dioxide in a tank includes load cells positioned between the legs of the tank and a surface. Each load cell includes a frame constructed from a folded metal plate so that a top panel, sides and ends are formed. A beam having proximal and distal ends is suspended from the top panel of the frame by its proximal end and a spacer. A platform support is positioned upon the distal end of the beam with a platform on top. The platform support passes through an opening formed in the top panel of the frame so that the platform is supported above the frame top panel. A leg of the tank is secured to the platform. A strain gauge circuit is mounted to the top surface of the beam and a summary board receives the signals from the strain gauge circuits of multiple load cells so that the quantity of liquid in the tank is determined. This quantity may be displayed and/or transmitted as telemetry to a centralized delivery truck dispatching facility.
