Additional Variable Information
All attributes are continuous, with the exception of the class attribute. Meter A (1) -- Flatness ratio (2) -- Symmetry (3) -- Crossflow (4)-(11) -- Flow velocity in each of the eight paths (12)-(19) -- Speed of sound in each of the eight paths (20) -- Average speed of sound in all eight paths (21)-(36) -- Gain at both ends of each of the eight paths (37) -- Class attribute or health state of meter: 1,2 Meter B (1) -- Profile factor (2) -- Symmetry (3) -- Crossflow (4) -- Swirl angle (5)-(8) -- Flow velocity in each of the four paths (9) -- Average flow velocity in all four paths (10)-(13) -- Speed of sound in each of the four paths (14) -- Average speed of sound in all four paths (15)-(22) -- Signal strength at both ends of each of the four paths (23)-(26) -- Turbulence in each of the four paths (27) -- Meter performance (28)-(35) -- Signal quality at both ends of each of the four paths (36)-(43) -- Gain at both ends of each of the four paths (44)-51 -- Transit time at both ends of each of the four paths (52) -- Class attribute or health state of meter: 1,2,3 Meters C and D (1) -- Profile factor (2) -- Symmetry (3) -- Crossflow (4)-(7) -- Flow velocity in each of the four paths (8)-(11) -- Speed of sound in each of the four paths (12)-(19) -- Signal strength at both ends of each of the four paths (20)-(27) -- Signal quality at both ends of each of the four paths (28)-(35) -- Gain at both ends of each of the four paths (36)-(43) -- Transit time at both ends of each of the four paths (44) -- Class attribute or health state of meter: 1,2,3,4
