LS300-B型便携式流速流量仪(简称便携式流速仪)是专门为水文站、厂矿、环保监测站、农田排灌、水文地质调查等部门在野外进行明渠流速流量测量而研制的。

LS300-B型便携式流速流量仪可搭配流速传感器使用，该传感器旋浆螺旋角、螺距、制作工艺和材料等分别进行了重新设计。测量明渠流速流量等参数。

测量原理：

流速测量：流速仪在水力推动下，其内置信号装置产生转数信号。从而，可根据某个单位时段内流速仪产生的信号总数，由以下公式计算出流速：v=a+b*R/T(m/s)(自动计算)

v一测流时段内平均流速(m/s)

b一旋桨(或旋杯)水力螺距(m)

a一的流速仪常数(m/s)

T一测流历时(s)

R—T时段内流速仪转子的总转数

对某个个体流速仪来说，b和a为定值。因此，测流时,只要测出T和R值，即可计算出流速。

流量测量：输入被测断面类型，并手工输入(或者通过辅助传感器测量)规则断面的水位、宽度计算断面面积，仪表更具Q=V*S测算流速Q值
