摘要
信息化的基础是传感器 ,传感器的精确度对于信息来说是至关重要的。以常见的几种流量传感器 (流量仪表 )为例 ,说明仪表在使用过程中精确度下降的原因、判断方法以及采取哪些措施予以补偿或修正。
The foundation of information transfer is transducer.The accuracy of transducer is very important.Taking a few common flow-transducer (flowmeter) as examples why the accuracy of elucidation flowmeter used descend,how to judge,what measure should be taken to repair or correct are described.
