摘要:
一对超声波传感器性能的一致性直接影响流量计量精确度。针对不同的超声波传感器性能一致性差的问题,从其特性入手分析几项关系密切的参数对它的影响,并为用于同一个流量计的一对传感器的选择提供理论依据。同时, 采用传输线路法、替代法以及变频激励信号等方法实现对超声波传感器.的测试,并给出了实现测试的具体电路设计方法。实验验证表明，,提 出的测试方法稳定、可靠,测试性能一致性好的一对超声波传感器可以保证流量计量精确度。
Abstract:
The accuracy of flow measurement could be affected by the consistency of the pair of ultrasonic sen-sors. In view of the problem of poor consistency of different ultrasonic sensors, this paper aimed to analyze theinfluence of several closely related parameters , and provide theoretical basis for the selection of the pair of sen-sors used in the same flowmeter. At the same time , the transmission line method , alternative method and vari-able frequency excitation signal were used to realize the test of ultrasonic sensors, and the specific circuit de-sign method to realize the test was given. The experimental results showed that the proposed method was stableand reliable, and a pair of ultrasonic sensors with good test performance consistency could ensure the flowmeasurement accuracy.
