LDM-51 智能化明渠流量测量系统——闸控一体化、全渠宽流量计是唯一款能直接测量过流断面平均流速的智能型明渠流量计。该系统与目前其他流量仪表测量方法相比，该系统是直接得到面平均流速的，后者得到的是线平均流速或者点平均流速。综合比较起来，该系统的测量精确度较高。
该系统提供不同环境下流量测量的完美解决方案，可以运行在一些恶劣环境下，包括规则和不规则渠道开放式、封闭式的断面流量、流速的测量。
全渠宽流量计可以测量液位、平均流速和累积流量；
可以精准测量不同形式的断面流速；
测量不受水中漂浮物、泥沙含量、水位变化、温度的影响；
流速传感器安装方便、对水流不产生阻力。标准断面不需要改造即可直接安装，安装施工难度小、费用低;
仪表显示功能：可同时显示水位、断面平均流速、断面瞬时流量、累计流量等;
配套闸门使用可实现精准的测控一体化，可测量闸前及闸后水位、闸门开启度等；
具有数据永久保存功能，可在长期断电的情况下保存设置参数和流量值;
仪表具有标准的modbus(RTU)输出的485接口、双路模拟量输入接口配套使用；
使用注意事项
1、安装位置要尽量选择在渠道或河道比较平直的地段，选择仪表规格接近渠道宽度。
2、智能化明渠流量测量系统的所有连接线要尽量短，尽量避开动力线，做好连接线的防水、防潮、防断、屏蔽处理，保证接线的正确无误。
3、配合闸控安装选择匹配口径的流量仪表。
