Flow rate
(Fully compensated mass and energy flow feature board only)
The
Flow
tab is used to configure the settings associated with the Flow Variable. Fluid and primary
element information which defines the flow calculation is configured using Engineering Assistant.
Figure 2-27. Variables - Flow Tab
Under the
Flow Rate Setup
heading, the type of flow calculation is indicated by the check boxes next to
either
Mass Flow Calculation
or
Volumetric Flow Calculation
. To edit the flow calculation type, select the
Configure Flow Calculation Type
button.
Edit the
Flow Rate Units
and
Damping
value as needed. The flow calculation within the device uses
undamped process variables. Flow rate damping is set independently of the measured process
variables.
Note
If the flow calculation type is changed, the totalizer will be stopped and reset automatically.
Under the
Low Flow Cutoff
heading, edit the current
Minimum DP Value
as needed. The unit for this
value is the user-selected DP unit. If the measured DP value is less than the minimum DP value, the
transmitter will calculate the
Flow Rate
value to be zero.
The
Sensor Limits
and
Minimum Span
can be viewed under the
Flow Rate Sensor Limits
heading.
