超聲波多普勒流量計(jì)是主機(jī)通過(guò)RS485采集超聲波多普勒流速儀的流速、水位和溫度，并根據(jù)現(xiàn)場(chǎng)的實(shí)情輸入各種渠道參數(shù)，利用渠道參數(shù)和采集的水位H（m）計(jì)算出過(guò)水面積S(㎡)，過(guò)水面積與流速V(m/s)相乘法計(jì)算出瞬時(shí)流量流量乘以累積時(shí)間計(jì)算出累積流量。多普勒流量計(jì)是屬于一款非接觸式的產(chǎn)品，它的結(jié)構(gòu)是分體式的，可以測(cè)量的范圍在0.03m/s~5.0m/s，測(cè)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(dá)+-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(shí)流量*時(shí)間差=累計(jì)流量
超聲波多普勒流量計(jì)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(jì)不僅在清水中可測(cè)量，在渾水中也可以測(cè)量。還擁有獨(dú)立的平臺(tái)服務(wù)器，數(shù)據(jù)傳輸準(zhǔn)確無(wú)誤。
