P47: - - - a Linearisation
Linearisation is the method of assigning requested (calibrated or calculated) level, volume or flow to values measured by the transmitter.
It can be used for instance if the sound velocity is not known (LEVEL⇒LEVEL) or in the case of tank with other shape than under 6.4 or open
channel other than under 6.5 (LEVEL ⇒ VOLUME or LEVEL ⇒ FLOW).
