Abstract

The pump regulation system uses a probe (5) for measuring the flow velocity of the pumped fluid, supplying a corresp. signal to a processor (6) for corresp. adjustment of the rotation rate of the pump drive motor. During a calibration process, the processor (6) records the measured flow velocity signals for adjustment of the pump (2) between a standstill and full load in discrete steps, to obtain a characteristic curve. If the flow system is altered the highest measured flow velocity is used to correct the full load value defined by the characteristic curve, with the remaining values corrected correspondingly.
