8.5.5 PV (flow) damping
LOI menu path Detailed Setup → Sig Processing → Damping
Primary variable damping allows selection of a response time, in seconds, to a step change
in flow rate. It is most often used to smooth fluctuations in output.
8.6 Configure special units
Special units are used when the application requires units that are not included in the flow
units available from the device. Refer to for a complete list of the available units.
8.6.1
Base volume unit
LOI menu path Basic Setup → Flow Units → Special Units → Base Vol Units
Base volume unit is the unit from which the conversion is being made. Set this variable to
the appropriate option.
8.6.2
Conversion factor
LOI menu path Basic Setup → Flow Units → Special Units → Conv Factor
The special units conversion factor is used to convert base units to special units. For a
straight conversion of units from one unit of measure to a different unit of measure, the
conversion factor is the number of base units in the new unit.
Example: If you are converting from gallons to barrels and there are 31 gallons in a barrel,
the conversion factor is 31.
8.6.3
Base time unit
LOI menu path Basic Setup → Flow Units → Special Units → Base Time Unit
Base time unit provides the time unit from which to calculate the special units.For
example, if your special units is a volume per minute, select minutes.
8.6.4
Special volume unit
LOI menu path Basic Setup → Flow Units → Special Units → Volume Unit
Special volume unit enables you to display the volume unit format to which you have
converted the base volume units.
Example: If the special units are abc/min, the special volume variable is abc. The volume
units variable is also used in totalizing the special units flow.
