流速仪 测量河流、湖泊和渠道等水体的水流速度的仪器。有机械、电测和超声三种类型。机械型以转子式为主，有旋桨式和旋杯式流速仪。电测型有电磁式流速仪。超声型有时差法和多普勒法流速仪。 流速仪一般适用于定点测时段平均流速。由磁式流速仪或一转多讯号的转子式流速仪能测瞬时流速，也可用作动船法测速。 仪器的测速范围一般为 0.03～5.00米/秒，适用水深一般为0.2～20米。1790年德国R.沃尔特曼制成转子式流速仪，用于流速测量。中国20世纪50～60年代制造使用的旋杯式和旋桨式流速仪，具有防水防沙性能良好的特点。流速仪的发展方向是非转子的电测技术、光学技术、超声波技术和遥测技术。（见彩图) 旋桨式流速仪 主要由旋桨、身架和尾翼三部分组成。旋桨内装有讯号触点和轴承转轴等，中国"25-1型"旋桨流速仪的转轴系统中有曲折的迷宫结构，内部充满轻机油，有较好的防水防沙性能，能在高流速和多沙河流中使用。旋桨式流速仪、旋杯式流速仪和旋叶式流速仪均属转子式流速仪，工作原理基本相同，是利用水流动力推动转子旋转，根据转动速度推求流速。公式为：
