FUEL LEVEL METER FOR INDUSTRIAL VEHICLES |
摘要 |
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. |
