超声多普勒流速仪是应用声学多普勒效应原理制成的测流仪,采用超声换能器,用超声波探测流速。测量点在探头的前方,不破坏流场,具有测量精度高,量程宽;可测弱流也可测强流;分辨率高,响应速度快;可测瞬时流速也可测平均流速;测量线性,流速检定曲线不易变化;无机械转动部件,不存在泥沙堵塞和水草缠绕问题;探头坚固耐用,不易损坏,操作简便等优点。 LSH10-1型超声波多普勒流速仪
本试验采用的仪器为美国SonTek公司生产的三维流速测量仪器声学多普勒流速仪(Acoustic Doppler Velocimeter)ADV.该仪器最大的特点是能够高精度的测量单点的三维流速,从而使得研究复杂三维水流现象,全面把握复杂水体水力特性成为可能.
