本文介绍了一种新型统计测量方法——相关测量技术(correlation method)。文章对测量基本理论及测量系统进行了说明,并介绍了用相关法测量燃油流量的实验。通过实测的数据、特性曲线分析了测量精度、产生误差原因及提高精度的途径。相关测量的特点在于传感器不必与流体直接接触,可以避免对流动状态的干扰,另外,它可以用于动态测量。因此,适用于某些特殊要求的场合。
This article describes a new statistical measurement method - the correlation method. The article describes the basic theory of measurement and measurement system, and introduces the experiment of measuring fuel flow by correlation method. Through the measured data, characteristic curve analysis of the measurement accuracy, the reasons for the error and improve the accuracy of the way. The relevant measurement is characterized by the sensor does not have direct contact with the fluid, to avoid interference with the flow of state, in addition, it can be used for dynamic measurement. Therefore, suitable for some special requirements of the occasion.
