A PROCESS OF MEASURING ACCURATELY A QUANTITY OF LIQUEFIED GAS OF THE TYPE HAVING A BOILING POINT AT ATMOSPHERIC PRESSURE BELOW 233* K. WHEN TRANSFERRED FROM A SUPPLY SOURCE AT LOW TEMPERATURE TO A RECEIVER THROUGH THE METERING ELEMENTS OF A VOLUMETRIC LIQUID METER ADAPTED TO REGISTER THE AMOUNT OF A LIQUEFIED GAS PASSED THERETHROUGH, WHICH PROCESS COMPRISES PROVIDING CONTINUOUS HEAT EXCHANGE BETWEEN A BODY OF SAID LIQUEFIED GAS AND THE METERING ELEMENTS OF SAID METER TO MAINTAIN SAID METERING ELEMENTS SUBSTANTIALLY AT THE TEMPERATURE OF THE LIQUEFIED GAS TO BE TRANSFERRED, SUCH CONTINUOUS HEAT EXCHANGE BEING ESTABLISHED PRIOR TO THE INITIATION OF ANY FLOW THROUGH THE METERING ELEMENTS; AND PASSING SAID QUANTITY OF LIQUEFIED GAS FROM SAID SOURCE THROUGH THE COLD METERING ELEMENTS TO SAID RECEIVER WHILE MAINTAINING THE PRESSURE ON SAID QUANTITY OF LIQUEFIED GAS DURING SUCH PASSAGE AT A VALUE AT LEAST SLIGHTLY HIGHER THAN ITS VAPOR PRESSURE AT THE TEMPERATURE OF THE LIQUID AT THE SOURCE, WHEREBY THE ACTUAL QUANTITY OF SAID LIQUID TRANSFERRED IS MEASURED AS LIQUID.
