在本公开的各种实施例中，应理解，下述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而 不应对本公开实施例的实施过程构成任何限定。
需要说明的是，相关技术中的连续液位计存在较大的不足。具体地，以多段霍尔液位计为例，其由磁性浮子和多段霍尔传感器(以下简称霍尔)组成，磁性浮子沿着导杆滑动，多段霍尔检测浮子位置，实现液位的测量，其中，多段霍尔的数量和排布长度决定了测量精度和测量量程，为了提高精度和量程，现有的多段霍尔一般贯穿整个水箱，而且霍尔的数量非常多，这导致液位计的成本很高。浮子一般放在水箱里，霍尔则有两种方案，放在水箱上或者放在机身上。当霍尔放在水箱上时，需要给霍尔提供无线供电和无线传输，成本很高。当霍尔放在机身上时，除了检测距离太大，容易失效的问题外，还有量程不够的问题。这是因为，为了提高容量，水箱一般都是高出机身的，高出机身的这部分水箱，机身上没有霍尔传感器，因此无法测量液位，限制了量程。
