Abstract:
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.
