DG-ADS-S10L10 Ultrasonic Doppler Flow Meter

The product employs the Doppler effect of underwater ultrasonic acoustics for measurement. The sensor emits a continuous, fixed‑frequency ultrasonic signal directly forward into the water and receives echoes reflected from acoustic scatterers—such as fine particles, bubbles, or impurities—that move with the flow. By analyzing the frequency shift of the received signal, the device calculates the velocity of the moving medium, which is then vector‑corrected to determine the water‑flow velocity. Meanwhile, a pressure transducer mounted at the sensor’s base detects changes in water pressure, yielding a water‑level signal. Combined with pre‑configured dimensions of the channel (e.g., river, pipeline), the cross‑sectional area of flow can be derived, enabling the calculation of discharge. An optional conductivity sensor may also be integrated to monitor water‑quality parameters.

Measurement principle

The product employs the Doppler effect of underwater ultrasonic acoustics for measurement. The sensor emits a continuous, fixed‑frequency ultrasonic signal directly forward into the water and receives echoes reflected from acoustic scatterers—such as fine particles, bubbles, or impurities—moving with the flow. By analyzing the frequency shift of the received signal, the device calculates the velocity of the moving medium; vector correction then yields the water‑flow velocity. Meanwhile, a pressure transducer mounted at the sensor’s base detects changes in water pressure, providing a water‑level signal. Combined with pre‑configured channel (or pipeline) geometry parameters, the cross‑sectional flow area can be determined, enabling the calculation of discharge. An optional conductivity sensor may also be integrated to monitor water‑quality parameters.

Key Features

Measurement parameters: flow velocity, water level, discharge, wetted cross-sectional area, water temperature, cumulative discharge, signal strength
Unidirectional flow (standard model): Does not distinguish between forward and reverse flow; the output is an absolute value. 0~ | ±10|m/S
Bidirectional flow (bidirectional model): Detects both forward and reverse flow and outputs values with positive or negative signs. -10~ 10m/S
Alloy plastic casing
Integrated conductivity sensor (optional)
Submersible hydrostatic level sensor (with built-in flow‑rate–dynamic pressure compensation)
Compact size, streamlined design

Application scenarios

Flow velocity and flow rate measurements for rivers, canals, and other waterways in hydrology, water resources, environmental protection, and municipal engineering; flow velocity and flow rate measurements at manholes; agricultural irrigation flow measurement; flow measurement at intake structures; flow measurement at discharge outlets; and non‑full‑pipe flow measurement in laboratory facilities.
