5.1.9 Density Setting
The density must be set in order to measure the mass flow rate. The density can be selected
from the fixed density or density corrected with temperature.
For details about how to measure the mass flow rate or correct the density by temperature, refer
to Subsection 5.5.5.
If density is set to “0” while the mass flow rate is mapped to PV, a setting error will result.
The setting can be configured with the following parameters.
