Abstract
A flexible conduit coupled to a chamber of a weighing apparatus for conduiting fluid to the chamber, the conduit having a portion attached to a support spaced apart from the load cell chamber and being sufficiently arcuate in shape between the point and the load cell to substantially reduce relaxation and/or weight effects of the conduit on weight measurements. In a preferred embodiment, the arcuate portion forms a semicircular arch.
