split balance weights to eliminate the effect of flow density

摘要

scale weights divided to eliminate the effect of flow density. a coriolis flow meter includes at least one flow conduit (103) including a first conduit node (603a) and a second conduit node (603b) and a curvature axis w which intersects the flow conduit (103). at the first conduit node (603a) and the second conduit node (603b). flow conduit 103 vibrates about the curvature axis w. The meter further includes a drive system (104) coupled to at least one flow conduit (103). scale system (600) includes two or more y scale weights (601a, 601b) and two or more fasteners (602a, 602b) that engage the two or more y scale weights (601a, 601b) in the at least one flow conduit (103). at least a first y-balance weight (601a) is coupled to at least one flow conduit (103) at a first location between the first conduit node (603a) and the drive system (104) and at least a second y scale weight (601b) is coupled to at least one flow conduit (103) at a second location between the drive system (104) and the second conduit node (603b).
