80.04 HQ curve Q1 Flow rate (in cubic meters per hour) at point 1 of the HQ
performance curve.
Parameters 80.04…80.13 define the HQ performance curve
of the pump for the flow calculation function. The H (head, or
level) and Q (flow rate) coordinates of five points on the
curve are entered. The values are provided by the pump
manufacturer. All points defined should lie within the
practical operating range of the pump.
Below is an example of an HQ performance curve. The
defining parameters of the first and last points are shown.
