Abstract

During the delivery or transport of liquids and/or gases by means of delivery units, a minimum residual cavitation by means of a regulating circuit is deliberately permitted. The cavitation is measured with the aid of a pressure sensor which transmits a voltage corresponding to the cavitation to a microprocessor. The latter controls the speed of the delivery unit used in such a way that a minimum residual cavitation is retained. <IMAGE>
