Method for determining volume stream in closed flow system i.e. heat circuit in wall-mounted heating system, involves determining stream from power correction value and theoretical power consumption characteristic curve for revolution speed
The method involves calculating actual power consumption and an actual power difference value of a flow machine i.e. heat circuit pump, during first and second revolution speeds (n1, n2) of the flow machine. Theoretical power difference value corresponds to the actual power difference value, during the respective revolution speeds. The actual and the theoretical power consumptions are utilized for formation of a power correction value. The volume stream is determined from the stored correction value and a theoretical power consumption characteristic curve for the third revolution speed.
