No.
Flowrate estimation
/ unit32
Selects the axis of Q-H pump curve that can be
interpreted as the output.
The user can choose the function to calculate either
actual Flow estimate out of input Head measurement
or actual Head estimate out of input Flow
measurement.
Function type85.79
0Function output is the flow estimate calculated from
the user given input interpreted as the total dynamic
head measurement.
Flowrate estimation
1Function output is the total dynamic head estimate
calculated from the user given input interpreted as the
flow measurement.
Head estimation
0.00 / real32Displays the Flow value for the next missing Head point
in the custom user curve.
This signal serves for input assistance.

10 = 1 / 100 = 1Q for the next H-point.0.00 ... 30000.00
0.00 / real32Displays actual flow rate calculated from the user
defined pump curve.
Note: In case parameter 85.79 Function type is set to
Head estimation, this signal displays the value used as
the input for the curve.
Flowrate actual85.91
10 = 1 / 100 = 1Flowrate actual.0.00 ... 30000.00
0.00 / real32Displays actual head calculated from the user defined
pump curve.
Note: In case parameter 85.79 Function type is set to
Flowrate estimation, this signal displays the value used
as the input for the curve.
