流速流量测算仪(简称便携式流速仪)是一种在水文测验中进行流速测量的通用型仪器,用于江河、湖泊、水库、水渠等过水断面中预定测点的时段平均流速的测量。
该流速仪符合GB/T 11826-2019(转子式流速仪)等相关国家标准。
该流速仪广泛适用于水文测验、水利调查、农田灌溉、径流实验等,亦可适用于水电、环保、矿山、交通、地质、科研院所、市政等行业进行相关流速或流量的监测。
便携式流速仪主要由LS1206B型旋桨式流速传感器、流速测算仪、0.4m×4Ф16测杆组成。全套仪器置于高铝合金密码箱内。接通信号线,即可进行各明渠中流速的测量,并自动显示流速。
该仪器结构简易、轻巧方便、耗电省、功能齐全、自动化程度高、稳定可靠,符合国家明渠流量测量标准,配置60度高温旋桨,是国内目新型的便携式流速测量仪器。
二、技术参数:

测速范围:0.06-8.00 m/s
测流误差:≤1.5%
输出信号:磁激式开关接点通断信号
信号数/转子转数:2/1(每转2个信号)
显示屏:4×16位液晶显示
测量方式:测杆定位测量(亦可缆绳悬挂定位测量)
温度范围:-25℃-55℃,湿度≤90%RH
电源:DC8.4V(充电电池),充满后可连续工作40小时以上
三、工作原理:
本仪器依据明渠测流的流速面积法原理设计,测出流速即可得流量Q=V·S(S为断面面积)
1.流速测定:
测流速时,由水力推动旋桨式转子流速仪旋转,内置信号装置产生转数信号,由下面公式计算流速:V=KN/T+C(m/s)(自动计算)
V:测流时段内平均流速(m/s)
K:桨叶水力螺距
C:流速仪常数
T:测流历时(单位为S)
N:T时段内信号数
本仪器使用时,K、C均为常数,测流时,只要测出T和N,即可算出流速。
2.流量的计算:
流量测定根据明渠流量测量的流速面积法,先测出流速再乘以断面面积即得流量。
