Abstract:

A flow rate meter correction device for fluid supply systems, wherein actual meter conditions and/or end use point conditions vary substantially from meter calibration conditions, having a variable length scale for indicating actual (corrected) flow in appropriate units means for calculating a correction factor reflecting the deviation of actual meter indication (pointer movement, etc) from meter indication under meter calibration conditions, and means responsive to the correction factor for interrelating the meter indicator with the variable length scale. The variable length scale indication is positionable relative to the meter indication by positioning means associated with the calculating means.
