Load cell and weighing system for cryogenic tanks

A system for weighing an object having a plurality of legs comprising:

• a) a plurality of load cells, each including:
• i) a frame having a top panel, said frame adapted to be positioned upon a surface with the top panel spaced from the surface;
• ii) a beam having a distal end portion and a proximal end portion, said beam attached to the top panel of said frame by the proximal end portion in a generally horizontal orientation so that the distal end is suspended;
• iii) said distal end of said beam adapted support one of said plurality of legs of the object and including means for securing the leg to the distal end;
• iv) a strain gauge circuit attached to said beam between said proximal and distal end portions;
• b) one each of said plurality of load cells positioned between one each of the plurality of legs and the surface;
• c) the strain gauge circuits of each of said plurality of load cells in communication with an electrical device;
• whereby the electrical device determines the weight of the object via signals received from the plurality of load cells.

A tank system comprising:

• a) a tank containing a quantity of liquid, said tank supported by a plurality of legs;
• b) a load cell position under each leg, each load cell including:
• i) a frame having a top panel, said frame adapted to be positioned on a surface with the top panel spaced from the surface;
• ii) a beam having a distal end portion and a proximal end portion, said beam attached to the top panel of said frame by the proximal end portion in a generally horizontal orientation so that the distal end is suspended;
• iii) said distal end of said beam adapted to support one of said plurality of legs of the object and including means for securing the leg to the distal end;
• iv) a strain gauge circuit attached to said beam between said proximal and distal end portions;
• c) the strain gauge circuits of each of said plurality of load cells in communication with an electrical device;
• whereby the electrical device determines the quantity of liquid within the tank via signals received from the plurality of load cells.

A load cell for determining the weight of an object comprising:

• a) a frame having a top panel, said frame adapted to be positioned upon a surface with the top panel spaced from the surface, and a floor-mount hole formed through the top panel of the frame, the floor-mount hole adapted to receive a bolt which is positioned there through and engagement with the surface upon which the load cell is positioned;
• b) a beam having a proximal end portion and a distal end portion, said beam suspended from the top panel of said frame by the proximal end portion;
• c) a strain gauge circuit attached to said beam between the proximal and distal end portions;
• and
• d) the distal end portion of said beam adapted to support the object.

A system for weighing a tank containing liquid carbon dioxide and having a plurality of legs comprising:

• a) a plurality of load cells, each including:
• i) a frame having a top panel, said frame adapted to be positioned upon a surface with the top panel spaced from the surface;
• ii) a beam having a distal end portion and a proximal end portion, said beam suspended from the top panel of said frame by the proximal end portion;
• iii) said distal end of said beam adapted support one of said plurality of legs of the tank;
• iv) a strain gauge circuit attached to said beam between said proximal and distal end portions;
• b) one each of said plurality of load cells positioned between one each of the plurality of legs and the surface;
• c) the strain gauge circuits of each of said plurality of load cells in communication with an electrical device;
• whereby the electrical device determines a quantity of liquid carbon dioxide in the tank based upon the weight of the tank via signals received from the plurality of load cells.
