<p>A system for dispensing cryogenic liquid (14) to a use device tank (64) from a bulk storage tank (10) containing a supply of cryogenic liquid (14) features a pump (30) in communication with the bulk storage tank (10), a dispensing line in communication with the pump (30) and a heater (52) in communication with the dispensing line. A system control device (82) controls the operation of the pump (30) and heater (52). A liquid level sensor (74) and temperature or pressure sensor (72) communicate with the use device tank (64) and the system control device (82). The system control device (82) calculates the appropriate amount of cryogenic liquid (24) and heat that should be added to the cryogenic liquid (14) as it is dispensed.</p> |
