水表的检定装置是在水表上装一个摄像装置将水流量情况传输到计算机中,然后计算机去对各个指针的水流量进行识别。检定装置一般都由普通的碳素钢材料制成,由于长期在水中工作,以及近年来来水质变差,腐蚀性增加,水表检定装置被腐蚀的现象比较普遍。检定装置的腐蚀导致其本身的测量精度降低。所以对于水表检定装置的技术改造工作显得尤为重要,笔者从目前普遍使用的检定装置出发对技术改造工作进行分析,提出一些自己的见解。
The water meter calibration device is equipped with a camera on the water meter to transmit the water flow to the computer, and then the computer to identify the water flow of each pointer. Verification devices are generally made of ordinary carbon steel material, due to long-term work in the water, as well as water quality deterioration in recent years, increased corrosion, water meter calibration device is more common phenomenon of corrosion. Corrosion of the verification device leads to a reduction of its own measurement accuracy. Therefore, it is very important for the technical reconstruction work of the water meter calibration device. Based on the commonly used verification device, the author analyzes the technical reform work and puts forward some own opinions.
