Selection No.
Estimates flowrate of pump curves in ESP application. Q-H pump curves 85
See section Pump curves.
Input 1 - Input 2 /
unit32 Selects the method for the pump curve input
processing.
The user has two source parameters for the pump curve
input (
85.02 Input 1 source and 85.03 Input 2 source ).
Pump curve input
function 85.01
The used input for the pump curve function could be
either of source parameters or result of math operation
between the two.
- Zero NULL
- Parameter 85.02 Input 1 source is input for pump curves
function.
Input 1 Direct
- Parameter 85.03 Input 2 source is input for pump curves
function.
Input 2 Direct
- Sum of 85.02 Input 1 source and 85.03 Input 2 source
is the input of pump curves function.
Input 1 + Input 2
- Difference of 85.02 Input 1 source and 85.03 Input 2
source is the input of pump.
Input 1 - Input 2
- Multiply of 85.02 Input 1 source and 85.03 Input 2 source
is the input of pump curves function.
Input 1 × Input 2
- Division of 85.02 Input 1 source and 85.03 Input 2 source
is the input of pump curves function.

0.00 Hz / real32 Defines Q-H pump curve frequency 1.
If there are several Q-H curves available from the pump
manufacturer, then set values for the fastest first. Curve frequency 1 85.04
10 = 1 Hz / 100 = 1 Hz Curve frequency in Hz. 0.00 ... 600.00 Hz
