随着能源计量、环境保护和交通运输领域的快速发展,许多新测量原理的流量测量方法和仪表被国内外开发出来,从而应用领域也有了很大拓展,进入许多过去的禁区,如可以不对管道作任何改动就可作非接触测量;过去某些流量仪表用来测量特殊对象的流量时感到很困难,如今因技术上有所突破而变得容易。但是,环保工程等新兴产业提出的要求,现有手段尚不能完全满足,亟待开发。 With the rapid development of energy measurement, environmental protection and transportation, many new measurement methods and instruments for flow measurement have been developed both at home and abroad. As a result, the fields of application have also been greatly expanded, entering many of the past restricted areas, for example, With any changes you can make non-contact measurements; in the past some flow meters were used to measure the flow of a particular subject, finding it difficult to do so now with technical breakthroughs. However, environmental protection projects and other emerging industries put forward the requirements of the existing means can not yet fully meet the urgent need to develop.
