Ultrasound converter for flow meter in liquid or gaseous medium, has electrodes at piezoelectric body defining overlapping area and contact points for electrodes are provided outside overlapping area

摘要

The ultrasound converter includes a piezoelectric body (13) with electrodes (4,3) on front and rear side. Contact points (5,6) for the electrodes are provided outside an overlapping area (7) at the piezoelectric body, which is defined by the electrodes. An Independent claim is also provided for an ultra sound meter detecting the flow of the medium.
