摘　　要：介绍了一种用于油田分层注水的流量计,该流量计采用分体式设计,分为井下测量仪和井上显示仪。详述了流量计的结构、工作原理和数学模型,分析了仪表系数非线性产生的原因,并给出了直线分段拟合的解决方法,还给出系统通讯的实现等内容。This paper introduces a kind of flow meter used in pouring water to the oil layer. The flow meter is separated to two parts. One is used in the lower part of the oil well. And the other is used in the higher part of the oil well to display the data. The structure, principle and mathematic model of the flow meter are described in detail. The reason of non-linearity of the instrument's coefficient is analyzed. And the solution is given. The communication of two parts is discussed.
