一种超声波流量计的超声换能器结构
摘要：
本发明公开了一种超声波流量计的超声换能器结构，包括两端封闭的管道，在管道的两端分别开设有一凹槽，在凹槽内沿其轴向设有两层换能元件以及三层金属电极片，在换能元件和金属电极片外侧设有绕换能元件和金属电极片一周的去耦层；所述换能元件、金属电极片以及去耦层由灌封层密封在凹槽内；在管道的侧壁上设有进液管和出液管，所述进液管和出液管分布靠近管道的两端。本发明结构简单，使用方便，并且稳定性高。
摘要（英）：

The invention discloses an ultrasonic transducer structure of an ultrasonic flow meter, which comprises a pipeline with the two ends thereof to be closed. The two ends of the pipeline are respectively provided with a groove. A two-layer transducer element and a three-layer metal electrode plate are arranged along the axial direction inside the grooves. The outer side of the transducer element and the metal electrode plate is provided with a decoupling layer that is arranged to surround the transducer element and the metal electrode plate for one circle. The transducer element, the metal electrode plate and the decoupling layer are sealed inside the grooves an encapsulation layer. The sidewall of the pipeline is provided with a liquid inlet pipe and a liquid outlet pipe. the liquid inlet pipe and the liquid outlet pipe are positioned at the two ends of the pipeline. The ultrasonic transducer is simple in structure, convenient to use, and high in stability.
