一、前言流量和温度、压力一样,也是最重要的计量量之一。随着工业技术的发展,要求的计量精度也日渐提高。作为计量对象的流体有液体和气体的区别,而且液体与气体的各自密度、粘度、温度、压力、腐蚀性及计量条件等又均不尽相同。所以,出现了各式各样的流量计,以适应流体的不同状况。 First, the foreword Traffic and temperature, pressure, is one of the most important measurement. With the development of industrial technology, the required measurement accuracy is also increasing. The fluid to be measured is the difference between liquid and gas, and the respective density, viscosity, temperature, pressure, corrosivity, and measurement conditions of the liquid and the gas are different from each other. So, there has been a wide range of flow meters to suit the different conditions of the fluid.
