Important
Actual flow direction interacts with Sensor Flow Direction Arrow to determine the flow direction that
the transmitter uses in processing. See the following table.
Table 6-1: Interaction between actual flow direction and Sensor Flow Direction Arrow
Actual flow direction
Forward (same direction as Flow
arrow on sensor)
Reverse (opposite from Flow arrow
on sensor)
4. Optional: Set User Name to the name you want to use for the inventory or totalizer.
User Name can have a maximum of 16 characters.
The transmitter automatically generates a name for each totalizer and inventory, based on its source,
direction, and type.
Example
• Totalizer Source=Mass Flow
• Totalizer Direction=Forward Only
• Totalizer name= Mass Fwd Total
Example
• Inventory Source=Gas Standard Volume Flow
• Inventory Direction=Bidirectional
• Inventory name= GSV Bidir Inv
The specified name is used on the transmitter display and on all interfaces that support it. If User Name
contains only spaces, the transmitter-generated name is used. Not all interfaces support totalizer and
inventory names.
Checking for backflow
You suspect that there is a significant amount of backflow through the sensor. To collect data, configure two
totalizers as follows:
• Source=Mass Flow, Direction=Forward Only
Source=Mass Flow, Direction=Reverse Only
•
Reset both totalizers, allow them to run for an appropriate period, then look at the amount of reverse flow as
a percentage of forward flow.
Tracking three different process fluids
Three tanks are connected to a loading dock through a single meter. Each tank contains a different process
fluid. You want to track each process fluid separately.
