    • A sensor apparatus for determining fluid levels and pressures in a fluid-containing vessel wherein the sensor apparatus comprises a mounting member having a fluid passageway positioned therein; a pressure sensor in operative contact with one end of the mounting member and a pressure fluctuation dampening device operatively positioned on the other end of the mounting member. The dampening device comprises an arrangement of fluid passageways arranged so that the fluid passageway through the mounting member substantially perpendicularly intersects a second fluid passageway intermediate the ends of the second fluid passageway with the second fluid passageway being intersected at each of its ends by third and fourth fluid passageways.
    • 一种用于确定含流体容器中的流体水平和压力的传感器装置,其中所述传感器装置包括具有定位在其中的流体通道的安装构件; 压力传感器与安装构件的一端可操作地接触,以及可操作地定位在安装构件的另一端上的压力波动阻尼装置。 阻尼装置包括流体通道的布置,其布置成使得通过安装构件的流体通道与第二流体通道的端部之间的第二流体通道基本上垂直相交,第二流体通道在其每个端部处相交,第三和第四 液体通道。
