Table 6-1: Interaction between actual flow direction and Sensor Flow Direction Arrow
Actual flow direction
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.
