- Commodity name: DG-ADS-R-S10L10 Ultrasonic Doppler Flow Meter
Measurement principle

The product employs an ADS underwater ultrasonic Doppler flow‑velocity sensor for measurement, leveraging the acoustic Doppler effect to determine flow velocity, measuring water level via pressure changes, and assessing water quality through conductivity. It integrates a built-in power‑management module, a sensor‑drive module, a power‑management module, and a communication module (supporting 4G or NB‑IoT).

Key Features

Measurement parameters: flow velocity, water level, electrical conductivity (optional), discharge, wetted cross-sectional area, water temperature, cumulative discharge, and 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. -10~10 m/s
Submersible hydrostatic level sensor
The host unit is equipped with an expansion bolt kit, enabling rapid installation at the wellhead.
The host features a stainless steel enclosure, offering excellent corrosion resistance, waterproofing, and impact resistance.
Rigid sealing, unaffected by temperature fluctuations.
Supports multiple lid openings without compromising waterproofing, making on-site battery replacement convenient.
A color local display unit accessory can be optionally added.

Application scenarios

Measurement of flow velocity and discharge in manholes; measurement of flow velocity and discharge in rivers, channels, and other waterways for hydrological, hydraulic, environmental protection, and municipal applications; measurement of irrigation discharge in agriculture; measurement of intake‑point discharge; measurement of effluent‑outlet discharge; and measurement of non‑full‑pipe flow in laboratory facilities.

Technical Specifications

Host: Stainless steel housing, IP68 rating, explosion-proof, wall-mounted for well installation.
Flow velocity accuracy: 1% ± 0.005 m/s
Flow velocity resolution: 0.001 m/s
Dead-zone velocity: Unidirectional model: |0–0.003| m/s; Bidirectional model: −0.006 m/s to 0 to 0.006 m/s
Water level range: 0–10 m, customizable
Water level accuracy: 0.2% FS ± 0.001 m
Water level resolution: 0.001 m
Water temperature range/accuracy: 0–60°C / 0.5°C
Conductivity range/accuracy: 0–10.000 mS/cm / 2% (optional)
Water temperature resolution: 0.1℃
Optional accessory 1: An external temperature sensor can be added, with an accuracy of 0.5°C and a resolution of 0.1°C.
Measurement range: -10~80℃
Optional accessory 2: A combustible (methane) gas concentration sensor can be added; however, this will reduce the device’s battery life.
Power Supply: Built-in lithium‑ion battery, non‑rechargeable; 133 Ah, 266 Ah, or 399 Ah at 3.6 VDC; self‑discharge rate not exceeding 5% per year.
Battery life: 5 minutes per measurement and transmission; each sensor operates for 5 seconds per cycle. The unidirectional version lasts 5 years, while the bidirectional version lasts 3 years (based on a 266 Ah battery).
Wireless breakpoint resumption: When the base station signal is interrupted, data is automatically saved and, once the wireless signal is restored, the timestamped data is resent.
Bluetooth (optional): BLE Low Energy 5.1, 150 meters in open space, sensitivity: -90 dBm, transmit power: +6 dBm, standby…
Current: 50 µA
Base configurations: rectangular, circular (factory preset), trapezoidal, elliptical, U-shaped, and other custom options.
Full-pipe detection: Automatically identifies the full-pipe condition and independently calculates the flow cross-sectional area.
