A15 Damping

Definition

• A15 Damping: Smooths flow measurement data. Default: 3.

• Higher value → smoother display, smaller fluctuations, slower response.

• Lower value → faster response, more sensitive to flow disturbances, larger fluctuations.

Notes

1. Process Monitoring Application: It is recommended to set A15 higher than the default value to improve display stability and readability, reducing the effect of short-term fluctuations on the displayed value.

2. Process Control Application: It is recommended to set A15 lower than the default value to minimize measurement delay, allowing flow changes to be reflected in the control system in real time.

3. Function Description: A15 only affects the smoothness of the display and output; it does not affect the actual measurement accuracy of the flowmeter.

4. Setting Confirmation: After adjusting A15, it is recommended to observe the system operation for several minutes to verify that the setting meets the application requirements.

5. Usage Reminder: Setting A15 too high may cause delayed response to flow changes. Adjust according to the actual application scenario.
