【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。更多还原

【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.更多还原
