Abstract

The invention relates to a centrifugal pump 1 or fan with electric motor for conveying a temperature-controlled fluid, in particular a canned-motor pump for a heating system, sensors being arranged to register the speed of rotation, the electrical current strength and/or the pressure differential, in order to determine the volume flow of the fluid, at least one sensor 4, 5 being arranged in order to register the temperature of the fluid, the measured values of which are input together with the measured values of the other sensors in an electronic computer 2, 8, 9 in order to calculate and output the heat throughput. <IMAGE>
