Configure density measurement

The density measurement parameters control how density is measured and reported.
Density measurement (along with mass measurement) is used to determine liquid volume
flow.
The density measurement parameters include:
•
•
•
•
(3) Refer to the digital communications status bits for an indication of whether flow is positive or negative.
