摘要： A combined liquid flow tube alignment and liquid sensing system includes flow tube mounting and alignment hardware including a clip for fastening the hardware to a substrate; and a sensor for sensing integrated with the liquid flow tube mounting and alignment hardware, wherein fluid flowing through a flow tube mounted and aligned by the flow tube The flow tube mounting and alignment hardware includes a clip with internal periphery edges sized to match the external periphery edges of at least one sensing element associated with the sensor. At least two posts located at outer members of the clip above and below the tube. Posts are sized to be located ideally within a system to position and retain the outer diameter of liquid flow tube with respect to internal periphery edges of the clip and subsequently, the sensing element both horizontally and vertically. A center flexing member associated with the clip. A slot to accurately position/retain and apply a controlled force to an area of the tube located at the center of the sensing element.

摘要： A disposable fluid flow sensor is disclosed herein, which generally includes a flow channel assembly comprising a flow channel tube in association with a disposable flow channel portion. A sensor die is located approximate to a thin interface or membrane formed from the disposable flow channel portion, such that the sensor die measures a flow of fluid flowing through the flow channel tube and the disposable flow channel portion of the flow channel assembly. Additionally, a substrate can be provided upon which the sensor die is formed and located. A seal can also be provided for sealing the disposable flow channel portion to the flow channel tube. Such a flow sensor can be implemented in the context of a “non-isolated” sensor die approach in which the sensor die, substrate and flow tube are assembled together into a complete disposable assembly, in which a thin interface does not cover the sensor die. The flow sensor can also be implemented in the context of an “isolated” sensor die approach in which a thin membrane material or thin interface prevents the fluid from touching the surface of the sensor die. In such an “isolated” configuration, the sensor die is not actually part of the disposable flow tube assembly. The only disposable portion in this approach is the flow tube itself.

摘要翻译： 本文公开了一次性流体流量传感器，其通常包括流动通道组件，其包括与一次性流动通道部分相关联的流动通道管。 传感器模具近似于由一次性流动通道部分形成的薄界面或膜，使得传感器模具测量流过流动通道管和流动通道组件的一次性流动通道部分的流体流。 另外，可以提供形成和定位传感器管芯的基板。 还可以提供密封件以将一次性流动通道部分密封到流动通道管。 这种流量传感器可以在“非隔离”传感器管芯方法的上下文中实现，其中传感器管芯，衬底和流管组装在一起成为完整的一次性组件，其中薄界面不覆盖传感器模具 。 流量传感器还可以在“隔离”传感器模具方法的上下文中实现，其中薄膜材料或薄界面防止流体接触传感器管芯的表面。 在这种“隔离”结构中，传感器模具实际上不是一次性流管组件的一部分。 这种方法中唯一的一次性部分是流管本身。
