Piece-Wise linearization- wet calibration
When the Piece-Wise linearization wet calibration method is selected, the meter uses a 12-point
piece-wise linearization on the dry-calibration velocity. Up to twelve flow rate and meter factor
pairs can be specified for each flow direction from the Daniel MeterLink
