The density correction calculation can be set using the following procedure.
(1) Set to the use of the temperature-corrected density by referring to Subsection 5.1.9.
(2) Set the function of the external temperature input function to the temperature by referring to
Section 5.4.
(3) Set the range high limit and low limit of the external temperature input by referring to Section
5.4.
(4) Set the standard temperature and standard density by referring to Subsections 5.1.9 and
5.1.10.
(5) Set the primary and secondary compensating rates of the compensation formula.
NOTE
The density correction calculation is performed only when items (1) and (2) above are specified.
If they are not specified, the density is assigned to the fixed value that is specified in Subsection
5.1.9.
Example:
If the water density is corrected based on the temperature in the following conditions, the result is
obtained as shown below.
Ext temperature input range = 0.0 to 100.0°C,
Standard density = 1000 kg/m
Standard temperature = 20°C,
Primary compensating rate = -0.02, Secondary compensating rate = -3.9
