Abstract: A method for controlling the power limit of a pump device includes controlling the power limit of the pump device on the basis of a pump media temperature Tm and an ambient temperature Ta measured inside a control box of the pump device. A pump device, in particular a centrifugal pump, is driven by a motor. The motor is controlled by a control box wherein temperature sensors for measuring a media temperature Tm and an ambient temperature Ta are arranged in the control box so as to control the power limit of the pump device depending on the measured media temperature Tm and an ambient temperature Ta.

Abstract: A computer-implemented method for determining a forward flow rate of fluid flow through a pump, the pump comprising an impeller and a pump motor, the forward flow rate being responsive to the impeller being driven by the pump motor to rotate in a forward direction and at a forward speed, the method comprising: obtaining an observed reverse power of the pump motor when the pump motor is operated to drive the impeller in a reverse direction, opposite the forward direction, and at a reverse speed; computing an estimate of the forward flow rate from at least the observed reverse power.
