Abstract: A measurement device determines a volume flow based on acoustic flow measurement methods in a pump system and a method produces the measurement device. The measurement device includes a measurement path with two coupling wedges with two sound transducers disposed on the coupling wedges. The pump system and the coupling wedges are made of metal or a metal alloy.
