Description
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 output is the flow estimate calculated from
the user given input interpreted as the total dynamic
head measurement.
Function output is the total dynamic head estimate
calculated from the user given input interpreted as the
flow measurement.
Displays the Flow value for the next missing Head point
in the custom user curve.
This signal serves for input assistance.
Q for the next H-point.
Displays actual flow rate calculated from the user
defined pump curve.
Note: In case parameter
Head estimation, this signal displays the value used as
the input for the curve.
Flowrate actual.
Displays actual head calculated from the user defined
pump curve.
Note: In case parameter
Flowrate estimation, this signal displays the value used
as the input for the curve.
Head actual.
Defines the pump curves status word.
