Ultrasonic Doppler Flowmeter User Manual - English Version

　　Ultrasonic Doppler FlowmeterThe host unit collects the flow velocity, water level, and temperature from the ultrasonic Doppler velocimeter via RS485, and various channel parameters are input based on actual site conditions. Using the channel parameters and the collected water level H (m), the cross-sectional area of flow S (㎡) is calculated. The instantaneous flow rate is obtained by multiplying the cross-sectional area by the flow velocity V (m/s), and the cumulative flow is obtained by multiplying the instantaneous flow rate by the accumulated time. The Doppler flowmeter is a non-contact product with a split structure. It can measure flow velocities ranging from 0.03 m/s to 5.0 m/s, with a flow velocity accuracy of ±2–3%. The water depth measurement range is 0.02–3 m or 0.02–10 m (minimum water depth: 30 cm), with an accuracy of ±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.

　　Thus: Q = V × S

　　Instantaneous flow × time difference = cumulative flow

　　Ultrasonic Doppler FlowmeterThe dimensions without mounting brackets are width × height × thickness = 200 × 215 × 90 mm.

　　Doppler FlowmeterIt can measure not only in clear water but also in turbid water. It also has an independent platform server, ensuring accurate data transmission.
