•
Flow Filter Damping establishes a maximum adaptive filter
value. Under stable flow conditions (flow that varies less than
the
Flow Filter Hysteresis entry) this adaptive filter will
increase the number of successive flow readings that are
averaged together up to this maximum value. If flow changes
outside of the
Flow Filter Hysteresis window, the Flow Filter
adapts by decreasing and allows the meter to react faster.
Increasing this value tends to provide smoother steady-state
flow readings and outputs.
•
Flow Filter Hysteresis creates a window around the average
flow measurement reading whereby if the flow varies within
that window, greater
Flow Filter Damping will occur. The
filter also establishes a flow rate window where
measurements outside of the window are captured by the
Bad Data Rejection Filter . The value is entered as a
percentage of actual flow rate.
Example:
If the average flow rate is 100 GPM and the Flow Filter
Hysteresis is set to 5%, a filter window of 95-105 GPM is
established. Successive flow measurements that are
measured within that window are recorded and averaged
in accordance with the
Flow Filter Damping setting.
