A system for dispensing cryogenic liquid to a use device tank from a bulk storage tank containing a supply of cryogenic liquid features a pump in communication with the bulk storage tank, a dispensing line in communication with the pump and a heater in communication with the dispensing line. A system control device controls the operation of the pump and heater. A liquid level sensor and temperature or pressure sensor communicate with the use device tank and the system control device and the system control device. As a result, the conditions of the cryogenic liquid initially in the use device tank may be used by the system control device to calculate the appropriate amount of cryogenic liquid and heat that should be added to the cryogenic liquid as it is dispensed so that the use device tank becomes substantially filled with saturated cryogenic liquid. A liquid level sensor may alternatively be used as the sole use device tank sensor.

1. A system for dispensing cryogenic liquid to a vehicle-mounted tank having sensors for determining a liquid level and a pressure or temperature in the tank comprising:a) a bulk storage tank containing a supply of cryogenic liquid; b) a pump in communication with the bulk storage tank; c) a dispensing line in communication with the pump so that cryogenic liquid may be pumped from the bulk storage tank to the vehicle-mounted tank; d) a heater in operative relation with the dispensing line; e) an interface in communication with the tank sensors so that conditions of cryogenic liquid initially in the vehicle-mounted tank may be determined; and f) a system control device in communication with the tank sensors via said interface, said pump and said heater so that appropriate amounts of cryogenic liquid and heat may be determined and added to the vehicle-mounted tank based upon the initial conditions in the vehicle-mounted tank so that the vehicle-mounted tank becomes substantially filled with cryogenic liquid at a desired saturated level.
