摘要：
A flow sensor sub-assembly includes a flow tube having a lumen, an outside diameter, a first end, and a second end. An inlet fitting includes a conical orifice sized for insertion in either end of the flow tube, such that an internal passage of the inlet fitting is coaxial and concentric with the lumen and the end of the flow tube abuts a shoulder. An outlet fitting includes a conical orifice sized for insertion in either end of the flow tube, such that an internal passage of the inlet fitting is coaxial and concentric with the lumen and the end of the flow tube abuts a shoulder. A first piezo element integrated with the inlet fitting is arranged at an upstream position of the flow tube assembly and a second piezo element integrated with the outlet fitting is arranged at a downstream position of the flow tube assembly.
摘要（中）：
流量传感器子组件包括具有内腔，外径，第一端和第二端的流管。 入口配件包括尺寸适于插入流管的任一端的锥形孔，使得入口配件的内部通道与内腔同轴并与流体管同轴并且与管的肩部邻接。 出口配件包括锥形孔，其尺寸适于插入流管的任一端，使得入口配件的内部通道与内腔同轴并同心，并且流动管的端部邻接肩部。 与入口配件集成的第一压电元件布置在流管组件的上游位置处，并且与出口配件集成的第二压电元件布置在流管组件的下游位置处。
