Piece-wise linearization calibration
The linear meter factor is determined by the PWL inputs, the flow direction, and the dry-
calibration gas flow velocity. If set to Piece-wise Linear" then the piece-wise linearization
flow rate and meter factor parameters are used to calculate the meter factor to be applied.
