    • The present application discloses a method for measuring pressurized liquid fuel level in a fuel tank used on a vehicle comprising measuring the pressure of the fuel to generate a pressure signal and measuring the temperature of the fuel to generate a temperature signal. A fuel level signal is determined from the pressure signal and the temperature signal and changes in the fuel level signal are determined over time. A first point of the fuel level signal indicating approaching emptying of the tank is identified when changes in the fuel level signal exceed a given value and the approaching emptying of the tank is signaled to an operator of the vehicle in response to identifying the first point. Also disclosed is a fuel level meter system comprising a display comprising a series of at least three light sources arranged in a generally vertical column with a bottommost one of the at least three light sources being of a first color and light sources above the bottommost one of the at least three light sources being of a second color.
    • 本申请公开了一种用于测量在车辆上使用的燃料箱中的加压液体燃料液位的方法,包括测量燃料的压力以产生压力信号并测量燃料的温度以产生温度信号。 根据压力信号和温度信号确定燃料油位信号,并且随时间确定燃料油位信号的变化。 当燃料水平信号的变化超过给定值并且响应于识别第一点而向车辆的操作者发出接近的排空时,识别指示接近排空的燃料油位信号的第一点。 还公开了一种燃料液位计系统,其包括显示器,其包括布置在大致垂直的列中的一系列至少三个光源,所述至少三个光源中的最底部的一个是第一颜色,并且最上面的光源 所述至少三个光源是第二颜色。
