Advanced commissioning
8.33 Calculating the energy saving for fluid flow machines
Flow characteristic
Figure 8-84
To set the characteristic, you require the following data from the machine manufacturer for
each speed interpolation point:
• The flow rate of the fluid-flow machine associated with the 5 selected converter speeds
• At constant speed, the power drawn which is associated with the 5 flow rates corresponds to
the line frequency and mechanical throttling of the flow rate.
