基于M-BUS的矿用超声波明渠流量计设计

摘要

In order to real-time control the open channel flow rate,effectively prevent the coal mine water trouble,using cut throat flume and none-touch measuring ultrasonic wave intelligent flow rate sensor to test the open channel flow rate.It shows the relations%为实时监控明渠流量,有效预防矿井水害的发生,采用无喉道槽和非接触测量的超声波智能流量传感器测量明渠流量,既给出了明渠实时流量与水头高度之间的关系,减少了淤积的泥沙对测量的影响,又提高了流量测量装置的稳定性。实验表明,超声波无喉道槽流量计的不确定度低于4%,符合国家的相关标准。
