Description
Defines Q-H pump curve frequency 2.
If there are several Q-H curves available from the pump
manufacturer, then set values for the fastest first.
Curve frequency in Hz.
Defines Q-H pump curve frequency 3.
If there are several Q-H curves available from the pump
manufacturer, then set values for the fastest first.
Curve frequency in Hz.
Defines Q-H pump curve frequency 4.
If there are several Q-H curves available from the pump
manufacturer, then set values for the fastest first.
Curve frequency in Hz.
Defines Q-H pump curve frequency 5.
If there are several Q-H curves available from the pump
manufacturer, then set values for the fastest first.
Curve frequency in Hz.
Defines scale coefficient for the Q-H pump curves.
Typically, the pump manufacturers specify Q-H curves
valid for water. Set the value corresponding to a
specific gravity of the pumped fluid.
Pump curve scale coef.
Defines curve 1 maximum Head value at the
corresponding Flow value of 0.
Head at 0 flowrate 1.
Defines curve 1 maximum Flow value at the
corresponding Head value of 0.
Maximum flowrate.
Defines curve 1 Head value for the Downthrust limit.
Downthrust head 1.
Defines curve 1 Flow value for the Downthrust limit.
Downthrust flowrate 1.
Defines curve 1 Head value for the Upthrust limit.
Upthrust head 1.
Defines curve 1 Flow value for the Upthrust limit.
Upthrust flowrate.
Defines curve 1 Head value at the corresponding Flow
value of 1/2 of the Downthrust zone, i.e. Head point at
1/2 of Flow interval 0 and parameter
flowrate 1.
DNT zone 50% head 1.
