A capacitive sensor based fuel level measurement approach for a lorry

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。

We presented a capacitive sensor based traditional float-variable resistor measurement approach. fuel level and the capacitance of a capacitive sensor fuel level measurement approach to compensate the defect of It detects fuel level based on the better linear relationship between 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.
