ABB ACQ580 - Flow Calculation and Protection

Parameters 269
80
80 Flow calculation and
protection
Actual flow calculation.
Note: Parameters are dynamically hidden based on selection
of flow calculation mode. Parameters are visible according to
the selection of parameter 80.13 Flow feedback function.
80.01 Actual flow Actual system flow that is either calculated from the pressure
difference, measured directly or estimated from the pump
curves.
The calculation method is selected with parameter 80.13
Flow feedback function.
See the control chain diagram on page 412.
