Abstract:
    The utility model relates to tester for liquefied gas weight in sphere used for liquefied gas weight measurement in sphere. Its characteristics are that it includes electric differential pressure transformer (DBC), first explosion prevention safety barrier (DFA1), radar hydraulic gauge (DBL), second explosion prevention safety barrier (DFA2) and industrial control computer (IPC). The output of electric differential pressure transformer (DBC) is connected with the first explosion prevention safety barrier (DFA1). The output of radar hydraulic gauge (DBL) is connected with the second explosion prevention safety barrier (DFA2). The outputs of the first and second explosion prevention safety barrier (DFA1, DFA1) are connected with the analog quantity data acquisition card (A/D) in the industrial control computer (IPC). The advantages of the utility model are that high measuring accuracy and it can get the true density value of the liquefied gas in sphere and the measurable result is reliable.
