| 摘 要： | 针对灌区用水计量模糊问题，开发了一种新型明渠流量仪。该设备先对水位进行编码，后送至微处理器，利用无喉道量水槽获得流量算法，进行流量计算并实时显示输出，同时对用水记录进行存储，方便查询。通过RS_485总线可以将数据远传到计算机进行分析和打印。该产品已应用在节水灌溉系统中，效果良好。

| Abstract: | The paper introduces a new open channel water flux measurement device that aims to resolve the problem of inaccurate water measurement in irrigation districts. This device encodes the water level first, and then sends it to the microprocessor. The water flow formula is gotten from the cut_throat flume. After flux calculating, the water flux is shown in real_time. At the same time, it stores the irrigation records for later query. Data can be transmitted to the remote computer for printing and analyzing on the RS_485 bus. This product has been used in the water_saving irrigation system and worked well. |
