Measurement Algorithm of Multi-channel Ultrasonic Water Meter with Weighting Coefficient

针对供水管道内复杂多变的流场,多声道超声波水表可以实际跟踪流量变化,尽可能地还原封闭管道内水流状态。通过引入权重系数,建立滑动窗口滤波函数,提出了一种用于多声道超声波水表计量的算法。实验证明,该算法可解决多声道计量问题,能有效提高水表的计量稳定性及计量精度。

In view of the complex and changeable flow field in the water supply pipeline, the multi-channel ultrasonic water meter can actually track the flow change and restore the flow state in the closed pipeline as much as possible. In this paper, an algorithm for measuring multi-channel ultrasonic water meter is proposed by introducing the weight coefficient and establishing the sliding window filter function. Experiments show that the algorithm can solve the problem of multi-channel measurement, and can effectively improve the measurement stability and accuracy of water meter.
