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.
1. Set up three totalizers, one for each tank.
2. Name the totalizers Tank 1, Tank 2, and Tank 3.
3. Configure each totalizer as required for the corresponding process fluid.
4. Stop and reset all three totalizers to ensure that the beginning values are 0.
5. When loading from a tank, start the corresponding totalizer, and stop it when the load is finished.
