摘要： AT LEAST TWO MANOMETER TUBES, EACH TUBE BEING CONNECTED BETWEEN TWO PROBES LOCATED AT DIFFERENT LEVELS IN A RESERVOIR. THE PROBES MAY BE INSUFFLATION TUBES CONNECTED TO A GAS SUPPLY. A SCALE MOVABLE IN RELATION TO THE MANOMETER TUBES CARRIES AT LEAST TWO SERIES OF CURVES, EACH ASSOCIATED WITH ONE OF THE TUBES. EACH CURVE IN EACH SEREIS REPRESENTS THE HEIGHT OF LUQID IN ITS ASSOCIATED MANOMETER TUBE FOR A GIVEN LEVEL OF LIUQID IN THE RESERVOIR FOR A DIFFERENT LIQUID DENSITY. A REGULATOR IS INTERPOSED BETWEEN EACH INSUFFLATION TUBE AND ITS MANOMETER TUBE FOR MAINTAINING THE FLOW OF GAS CONSTANT THROUGH THE INSUFFLATION RUBES.
