基于电容式传感器的载重汽车燃油液位测量方法

针对传统的浮子-可变电阻方法测量燃油量的缺陷，提出了一种基于电容式传感器的燃油量液位测量方法，根据燃油液位与电容传感器的电容值成良好的线性关系测量液位。实验室测量结果表明，采用该方法燃油液位和传感器电容具有较好的线性度，测量误差小于±5%，耗电量低，使用寿命长。

A capacitive sensor based fuel level measurement approach for a lorry

We presented a capacitive sensor based fuel level measurement approach to compensate the defect of traditional float-variable resistor measurement approach.It detects fuel level based on the better linear relationship between fuel level and the capacitance of a capacitive sensor.Experimental results show that better linear relationship exists between fuel level and the capacitance of a capacitive sensor,less than ±5% measurement error.It has such benefits as less power consumption and long lifetime.
