Cryogenic fluid reporting systems and methods

A portable cart configured to determine and report an amount of cryogenic liquid in a cryogenic fluid tank, the portable cart comprising:

• a tank support configured to receive and support the cryogenic fluid tank;
• a frame comprising a base plate and a plurality of caster wheels;
• a plurality of load cells positioned between the tank support and the frame, the cart configured such that the weight of the cryogenic fluid tank on the tank support is applied to the plurality of load cells;
• wherein at least one of the plurality of load cells comprises an overload protected load cell, the overload protected load cell comprising:
• an upper member configured to contact the tank support;
• and
• a lower member that is spaced apart from the base plate by a gap when no weight is applied to the overload protected load cell;
• the overload protected load cell being configured such that, in response to an overload of weight being applied to the overload protected load cell, the overload protected load cell deflects such that the lower member contacts the base plate;
• a controller in communication with the plurality of load cells, the controller configured to receive a signal from each of the load cells indicative of the weight of the cryogenic fluid tank and to determine, based on the signals, an amount of cryogenic liquid in the cryogenic fluid tank;
• and
• a transmitter in communication with the controller.
