Claim 1
Independent Claim
135 words
IN A TANK CONTAINING A CRYOGENIC FLUID SUBJECT TO DENSITY VARIATIONS FROM ONE LOCATION TO ANOTHER WITHIN THE VOLUME THEREOF, A PLURALITY OF DENSITY PROBES IMMERSED IN SAID FLUID WITH ONE PROBE AT EACH OF SAID LOCATIONS, EACH PROBE COMPRISING A SOURCE OF BETA RADIATION, A SOLID-STATE RADIATION DETECTOR, AND MEANS FOR MOUNTING SAID DETECTOR WITHIN THE VOLUME OF SAID FLUID AND SUBSTANTIALLY SURROUNDED THEREBY, SAID MOUNTING MEANS INCLUDING MEANS FOR MAINTAINING A SPACING BETWEEN SAID DETECTOR AND SAID SOURCE WHICH IS WITHIN THE PENETRATION RANGE IN SAID FLUID OF BETA RADIATION FROM SAID SOURCE WHEREBY SAID DETECTOR IS ADAPTED TO PROVIDE AN OUTPUT SIGNAL INDICATIVE OF THE LOCAL DENSITY OF SAID FLUID AT A RESPECTIVE LOCATION, SUMMING CIRCUIT MEANS FOR COMBINING SAID OUTPUT SIGNALS FROM SAID PLURALITY OF DETECTORS TO PRODUCE AN AGGREGATE SIGNAL
