超聲波多普勒流量計是主機通過RS485采集超聲波多普勒流速儀的流速、水位和溫度，并根據現場的實情輸入各種渠道參數，利用渠道參數和采集的水位H（m）計算出過水面積S(㎡)，過水面積與流速V(m/s)相乘法計算出瞬時流量流量乘以累積時間計算出累積流量。多普勒流量計是屬于一款非接觸式的產品，它的結構是分體式的，可以測量的范圍在0.03m/s~5.0m/s，測量的流速精度在+-2~3%，水深范圍在0.02~3m；0.02~10m（最小水深：30cm），水深的精度可達+-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
瞬時流量*時間差=累計流量
超聲波多普勒流量計不帶安裝固定配件的尺寸為寬度×高度×厚度=200×215×90mm
多普勒流量計不僅在清水中可測量，在渾水中也可以測量。還擁有獨立的平臺服務器，數據傳輸準確無誤。
