A PWM signal is generated based on a reflection of an ultrasonic signal output by the ultrasonic sensor. The PWM has a period, and a plurality of pulses. Each pulse encodes a predetermined parameter and has a width. The PWM signal encodes the fluid level, fluid temperature, fluid speed of sound, and a status of the ultrasonic transducer. The PWM signal is received at a processor. The processor performs the diagnostic assessment of the ultrasonic sensor based on the period of the PWM signal and the widths of the plurality of pulses of the PWM signal.

摘要： Systems and methods for determining a plurality of characteristics of a fuel and controlling a fuel delivery system based on the characteristics of the fuel. A controller generates a plurality of control signals. The control signals are transmitted to at least one ultrasonic transducer, a capacitance sensor, and a temperature sensor. Each of the ultrasonic transducer, capacitance sensor, and temperature sensor generate at least one output signal which is transmitted back to the controller. The controller determines, based on the output signals, the plurality of characteristics of the fuel. The characteristics of the fuel can include, for example, temperature, density, dielectric constant, and the like. The controller then compares the characteristics of the fuel to a set of characteristics of a first fuel type and a second fuel type and controls a fuel delivery device based on the characteristics of the fuel.
