Measuring range
A Set the parameter 'Unit Volume Qv' to 'Custom Selectable'.
B In parameter 'Unit Name', enter the desired names for the standard

volume unit 'sm /d'.
C In parameter 'Unit Factor', enter the factor in l/s for the standard volume
3
unit 'sm /d' (in the example 86.4 l/s).
D Set the parameter 'Unit Density' to the desired density unit (in the
3
example kg/m ).

).
F Set the parameter 'Unit Density' to the desired density mode (in the
example Density fixed value).
G In parameter 'Density fixed value', enter the standard density of the
measuring medium (in the example 0.71680 kg/m
G In parameter 'Density cut off', enter the density for the cutoff of the
calculation (in the example 0.50 kg/m3). Adjust the parameter 'Density
Low Check' afterwards as needed (see page page 112).
