60 ESP program features
Pump curves
Q-H pump curves typically provided by the pump manufacturer can be used for the
actual flow rate estimation, provided that total dynamic head measurement is
available. You can connect both, intake and discharge pressure measurement signals
directly to the drive through analog inputs of Fieldbus.
ESP control program allows you to enter up to five Q-H curves for the pump running
at corresponding frequencies. The flow estimate calculation is then completed based
on motor actual speed and head (pressure) measurement input. For the speeds
beyond the frequency range covered by the pump curves, the flow estimate is then
based on affinity law.
Note:
In case actual flow rate is already measured with a flow-meter, then you can
configure the same Q-H curves to be used opposite way around, i.e. for indirect
estimate of the total dynamic head.
