Flow measurement using concentrated salt water as non-radioactive tracer in sewage pump
-
摘要: 针对污水泵流量监测中常规测流方法的缺点,结合工程实践,研究浓盐水示踪法在污水泵流量监测中的可行性,提出该方法适于在低背景盐浓度下污水的测流;观察激励信号、温度等对测流结果的影响,给出修正方法;利用计算机采集技术,提高方法的准确性、实时性。Abstract: Taking account of the defects of routine measurements of water flow on sewage pump,the feasibility study about the method using as non-radioactive tracer was made from the theory and the practice.It was shown that the method was suitable for sewage measurement under the background of low salt density.The effects of exciting signals and temperature on results were observed.Then the revision method were proposed With the technique of data acquisition by computer,the accuracy and synchrony of this method were improved.
