MXS05H Ultrasonic Doppler Current Profiler (H-ADCP)

The MXS05H is a horizontal side‑mounted Acoustic Doppler Current Profiler (H‑ADCP) designed for cross‑sectional flow monitoring in rivers, canals, and similar waterways. It enables stratified measurements of current velocity, water level, and water temperature, and directly outputs the cross‑sectional mean velocity and discharge.

I. Core Principles

   Based on the acoustic Doppler effect: two beams emit high-frequency sound waves into the water, which are scattered and reflected by suspended sediments, bubbles, and other scatterers; by analyzing the frequency shift of the returned echoes, the flow velocity in each layer is calculated; combined with water level and cross‑sectional parameters, the discharge is automatically determined.

II. Model and Key Parameters

III. Core Functions

Cross-sectional velocity measurement: horizontal coverage of the entire cross-section, with 256 layers simultaneously measuring flow, enabling detailed characterization of the lateral velocity distribution.
 

Water Level–Discharge Integration: Simultaneously measures water level and water temperature, automatically calculates average flow velocity, and computes instantaneous and cumulative discharge.

Remote online monitoring: Integrates with the Moxing Cloud platform, supports 4G/5G data upload, and enables remote configuration and debugging.
 

Pose Compensation: Built-in tilt sensor (accuracy ±0.5°) automatically corrects installation tilt errors.
 

IV. Structure and Installation
 

Probe: Planar array with dual beams, beam separation of 130°, directivity half-power beamwidth of 1.4°, and strong resistance to environmental interference.
 

Installation: Rail‑mounted on the riverbank side, with the probe positioned at least 30 cm above the water surface and in water depths of at least 1 m; maintenance requires no wading.

V. Typical Applications,

Online monitoring of flow rates in natural rivers, artificial channels, and water supply conduits.

Long-term monitoring of flow velocity and discharge in hydropower plant intake channels and reservoir outlets.

Flood and drought prevention, water resource allocation, and the upgrade of automated flow‑measurement systems at hydrological stations.

VI. Product Advantages

Maintenance-free: Side-mounted design eliminates the need for underwater operations, reducing operation and maintenance costs.

High precision: 0.001 m/s resolution, ±0.5% velocity error, compliant with hydrological surveying standards.

Wide‑range compatibility: coverage from 20 to 100 meters, with adjustable layering from 0.5 to 5 meters, suitable for rivers of varying widths.

Low power consumption: <1.5 W (2 M), enabling long-term operation powered solely by solar energy.

VII. Selection Recommendations

For river widths ≤20 m and water depths ≤5 m: select the MXS05H-2M (high frequency, with finer layering).

River width 20–100 m, water depth 5–10 m: select MXS05H-500K (low frequency, longer coverage).

VIII. Product Summary

The MXS05H ultrasonic Doppler profiler leverages mature acoustic velocity‑measurement technology and incorporates a domestically optimized design, offering four key advantages: high precision, exceptional stability, low maintenance, and easy integration. It can fully replace traditional rotary current meters and single‑point radar flow‑measurement devices, making it an ideal solution for modern water‑resources information systems and ecological‑flow monitoring.

The preferred monitoring equipment for control and refined management of water resources.
