Claims

1. AN ARRANGEMENT DOR THE CONTINUOUS SAMPLING OF A LIQUID GAS TAPPED FROM A TANK AND EVAPORATING THE TAPPED LIQUID INTO A GAS FOR ANALYSIS THEREOF, AND COMPRISING A FILTER CHAMBER POSITIONED WITHIN A BODY F A LIQUID GAS CONTAINED IN A TANK, A PIPE EXTENDING FROM SAID FILTER CHAMBER THROUGH SAID BODY OF LIQUID GAS WITH ONE END OF SAID PIPE PROJECTING A SHORT DISTANCE OUTWARDLY OF A WALL OF THE TANK, SAID PIPE HAVING A REDUCED DIAMETER PORTION THEREIN, A TUBULAR EVAPORATOR HAVING LOW-FLOW RESISTANCE WITH THE UPPER END THEREOF RECEIVING THE PROJECTING END OF SAID PIPE, MEANS ON SAID EVAPORATOR FOR HEATING THE SAME TO EVAPORATE TH ELIQUID GAS THEREIN CENTERING THROUGH SAID PIPE, THE LOWER END OF SAID EVAPORATOR HAVING A CONTROL VALVE THEREIN AND CONNECTED TO A GAS ANALYZER.
