Technical Examples
A method for detecting the undesirable entry of oxygen into a transfer system that transfers liquid hydrogen from a liquid hydrogen source into a container. A nozzle for use in the transfer system for dispensing liquid hydrogen comprises a housing and an oxygen sensor positioned inside the nozzle for detecting the concentration of oxygen in the nozzle when the liquid hydrogen is not flowing. The sensor emits a signal indicative of the concentration of oxygen in the transfer system before the liquid hydrogen begins transferring. The signal is received by a controller and prevents transfer of liquid hydrogen until the oxygen is removed from the transfer system.
