摘要
针对矿井水中含有的煤粉、泥沙等杂质淤积在明渠流量计探头表面而使其无法正常工作的问题,设计了一种基于M-Bus的矿用超声波明渠流量计。该流量计由量水堰槽、智能超声波流量传感器组成,选定量水堰槽可确定实时流量与实测水头高度的关系式,通过智能超声波流量传感器测出水头高度即可计算出明渠的实时流量。实际应用表明,该流量计具有测量准确、可靠性高、操作简单等优点。
In view of problem that open-channel flowmeter can't work normally because mine water contains impurities of coal powder and sediment which deposit on surface of probe of open-channel flowmeter,a mine-used ultrasonic open-channel flowmeter based on M-Bus was designed.The flowmeter is composed of water-level weir slot and intelligent ultrasonic flow sensor,which can get formula between real-time flow and measured height of water head by water-level weir slot and calculate real-time flow by intelligent ultrasonic flow sensor to measure height of water head. The actual application showed that the flowmeter has advantages of accurate measurement,high reliability and simple operation.
