To enter an internal damping value, use the menu below and follow these steps:
1. At the online menu, choose 4 (detailed setup).
2. At the detailed setup menu, choose 2 (configure field device variables).
3. At the configure field device variables menu, choose 1 (flow).
4. At the flow menu, choose 4 (flow damping).
5. Select the desired damping value.
6. Press F2 (send) to send the damping value to the flowmeter memory.
6.2.5 Flow direction
The configured flow direction (forward, reverse, or bi-directional) determines how flowmeter outputs
and totalizers will react when fluid flows through the meter. The flow direction arrow on the meter is
considered the "forward" flow direction, but the meter measures flow accurately in either direction.
To configure flow direction for the meter, use the menu below and follow these steps:
1. At the online menu, choose 4 (detailed setup).
2. At the detailed setup menu, choose 2 (configure field device variables).
3. At the configure field device variables menu, choose 1 (flow).
4. At the flow variables menu, choose 3 (flow direction), then choose the desired option. The
table below lists how outputs and totalizers are affected by the option that is chosen.
5. To send the flow direction to the flowmeter, press F2 (send).
