超声波多普勒流量计是主机通过RS485采集超声波多普勒流速仪的流速、水位和温度，并根据现场的实情输入各种渠道参数，利用渠道参数和采集的水位H（m）计算出过水面积S(㎡)，过水面积与流速V(m/s)相乘法计算出瞬时流量流量乘以累积时间计算出累积流量。多普勒流量计是属于一款非接触式的产品，它的结构是分体式的，可以测量的范围在0.03m/s~5.0m/s，测量的流速精度在+-2~3%，水深范围在0.02~3m；0.02~10m（最小水深：30cm），水深的精度可达+-5%。
Product Introduction
The product is a kind of sensor that measures flow velocity and flow rate in natural waters, channels or pipes.
The flowmeter is divided into two parts: sensor and host, connected by cable.
To be able to measure flow velocity and flow rate in channels and rivers, the water level has to be 20 cm higher than the sensor.
To be able to measure flow velocity and flow rate in pipeline and culvert, water level has to be more than 20 cm higher than the sensor, tubing inner diameter has to be ≥500 mm.
由此可知：Q=V*S
瞬时流量*时间差=累计流量
超声波多普勒流量计不带安装固定配件的尺寸为宽度×高度×厚度=200×215×90mm
多普勒流量计不仅在清水中可测量，在浑水中也可以测量。还拥有独立的平台服务器，数据传输准确无误。
