Abstract:
A system for dispensing a cryogenic liquid includes a storage tank containing a supply of the cryogenic liquid and a metering chamber. A liquid inlet line is in communication with the storage tank and the metering chamber so that the metering chamber receives cryogenic liquid from the storage tank. A meter run is in communication with the metering chamber and includes a metering element, a dispensing line and a dispensing valve. A stabilizing column is positioned within the metering chamber and includes vertically spaced openings. Vertically spaced first and second pressure sensors are in communication with the interior of the stabilizing column. A controller is in communication with the metering element, the first and second pressure sensors and the dispensing valve.
