Patent Images
1. A measurement device for determining a volume flow based on acoustic flow measurement methods in a pump system, the measurement device comprising:
- a first acoustic measurement path with first and second coupling wedges with a first sound transducer disposed on the first coupling wedge and with a second sound transducer disposed on the second coupling wedge, the first acoustic measurement path being disposed in a radial direction or in an axial direction or in a diagonal direction,wherein the pump system and the coupling wedges are made of metal or a metal alloy,wherein the first and second coupling wedges are milled out from a housing or from an inlet or an outlet,wherein a wall thickness in a region between the first coupling wedge and the second coupling wedge is reduced compared to a wall thickness in a region outside the first coupling wedge and the second coupling wedge, andwherein a groove is milled into a wall between the first coupling wedge and the second coupling wedge.

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.
