中文摘要:
      首先介绍了高精度油水界面计的原理,通过分析找到了影响其精度的重要因素为长度测量的不准确,用神经网络逼近测量结果,取代直接解析计算,得到了系统误差小于1mm的测量精度.
英文摘要:
      In the paper the principle and measuring method of high accuracy ultrasonic oil water interface meter are introduced,followed by its accuracy analysis.In order to eliminate the influence of incorrectness of the length measurement to the accuracy of interface height,a forward neural network is used to simulate the height equation.The result shows that the accuracy is better than 1mm
