Density correction If calibration is carried out with water, or if the product changes, the calibration can be
simply corrected by entering a density factor.
new density
density factor = effective factor • ––––––––––––
old density
Determining the density
factor Example: A vessel is filled with water and then calibrated. The density of water (old
density) is 1 g/cm
3
. The vessel will be later used as a storage tank and filled with the new
medium to be measured. The new density is 1.2 g/cm
3
. V3H4 still contains the factory
setting of 1, i.e. the actual factor is 1.

•
The measurement value in V0H0 is
divided by the density factor and thus
calibrated to the new product.
Note!
The density factor affects level measurement. When changing the product density,
please note that an existing linearisation curve can only be used with the new density
factor.
