随着我们国家经济的不断发展以及工业技术的发展,计量仪器技术在我们国家现在已经达到了一个很高的水准。水流量表则是这些计量仪器当中的一个十分重要的组成部分。在当前的现场管路上,这些仪表因为其本身所具有的特殊性构建,这就要求我们在进行周期性实验检定当中有着很高的精度,而这全桥是最难的一个部分。随着时代的进步,采用现场校对校准的方式对水流量表进行不确定度的评定已经成为了当前的一个十分迫切的需求。因此,我们根据现场环境的不相同情况,因地制宜,排除问题的所有要点,找出在这其中最为有效的方法是十分重要的。
With the continuous development of our country’s economy and the development of industrial technology, measurement instrumentation technology has now reached a very high standard in our country. Water meters are a very important part of these meters. In the current on-site pipeline, these instruments because of its own particularity built, which requires us to carry out periodic experiments with high accuracy, which is the most difficult part of the bridge. With the progress of the times, the use of on-site proofing and calibration of the uncertainty of the water flow meter assessment has become a very urgent need. Therefore, it is very important for us to find out the most effective methods in this respect according to the different circumstances of the site environment, eliminate all the points of the problem according to local conditions.
