MXS05RU Radar-Ultrasonic Flow Meter

I. Product Overview
The MXS05RU is an integrated dual‑mode, non‑contact flow‑monitoring device that combines radar and ultrasonic technologies. Designed specifically for municipal drainage networks, stormwater–sewage manholes, rivers, outfalls, and open‑channel ecological waterways, it leverages both radar‑based velocity and distance measurement and ultrasonic Doppler velocity measurement to address the limitations of standalone radar or ultrasonic sensors—such as poor performance at low flow rates, high water levels, interference from floating debris, and measurement blind spots. By enabling precise flow measurement across both full‑pipe and partially filled conditions, it serves as a core front‑end monitoring instrument for smart drainage systems, sponge cities, and water‑environment supervision.
The device is mounted via overhead suspension, remaining entirely above the water surface throughout operation, thereby eliminating the risk of sediment entanglement and clogging. The entire unit features low‑power consumption and potting‑type encapsulation, supports both wired and wireless remote data transmission, and is well suited for unattended, long‑term online monitoring.

II. Core Measurement Principle
1. Radar Doppler module: non-contact measurement of surface water velocity and millimeter-wave radar-based water level sensing; unaffected by water turbidity, sediment, or floating debris, making it suitable for medium to high flow velocities, open‑channel rivers, and large‑diameter pipe networks, with stable performance in rainy, snowy, and foggy conditions.
2. Ultrasonic Doppler module accurately captures cross‑sectional flow velocity under low flow rates and high submergence conditions, addressing the limitations of radar-based measurements at low water levels. Equipped with an integrated intelligent fusion algorithm, the device automatically identifies water level and flow regime, seamlessly switching to the optimal measurement mode and eliminating measurement blind spots.
3. Flow Calculation Logic: Equipped with a built-in cross-section library (rectangular, circular, and trapezoidal channels/pipes), it collects dual-mode flow velocity and water level data in real time and automatically computes, using the velocity–area method, instantaneous flow rate, cumulative volume, average flow velocity, real-time water level, and water temperature—providing a complete set of hydrological data.
III. Core Product Advantages
1. Dual-mode complementarity, with no blind spots across all operating conditions: Radar and ultrasonic sensors work in tandem to deliver stable measurements under low‑speed stagnant water, full‑pipe conditions at high water levels, the presence of large floating debris, and high‑sediment wastewater, covering 99% of flow regimes in municipal pipe networks.
2. Non-contact, ultra-low-maintenance operation: The device is hoisted and installed from the wellhead top, eliminating the need to enter the water or interrupt pipeline flow; with no submersible probes, it prevents aquatic vegetation entanglement and sediment encasement, significantly reducing annual maintenance workload.
3. All‑weather, highly protective housing: integrally pot‑sealed for complete waterproofing and dust resistance (IP68), with a corrosion‑resistant, aging‑proof enclosure; operating temperature range: –25°C to 55°C, suitable for extreme cold, intense sunlight, and damp underground manhole environments.
4. Wide measurement range and high accuracy: Capable of handling both weak, slow flows and high‑velocity storm‑water flows, with flow velocity and water level measured at millimeter‑level resolution; exhibits excellent data linearity and requires no complex on‑site calibration curves.
5. Low power consumption and easy installation: Ultra-low power, compact size, convenient for on-site installation, and fully suitable for pipeline network deployment.
6. Enhanced communication: The platform comes standard with RS485 (Modbus‑RTU protocol) and offers optional 4G/NB‑IoT wireless transmission, local storage of historical data, and seamless integration with smart water‑management cloud platforms, pump‑station automation systems, and environmental online monitoring platforms.
7. Intelligent anti-interference algorithm and smart flow‑rate algorithm; parameters such as transmit power and sensitivity can be adjusted according to actual conditions, ensuring compatibility with a variety of pipeline and trench environments.
IV. Typical Application Scenarios
1. Municipal drainage network: combined stormwater–sewage system, main sewage trunk lines, residential area discharge outlets, and online flow monitoring at intercepting sewer inlets.
2. Water Environment Management: river‑channel discharge outlets, ecological flow monitoring, rural sewage channels, and open irrigation canals.
3. Urban Flood Prevention and Drainage: Integrated monitoring of water levels and flow rates at road flooding hotspots, stormwater drainage networks, and pump station forebays.
4. Irrigation Districts: Agricultural diversion channels, reservoir spillways, and flow measurement at small sluice gates and dams.
5. Online Environmental Monitoring: Verification of pollutant discharge flow rates at source outlets and traceability-based measurement of total wastewater volumes.
V. Installation and Accessories  
1. Comes with a dedicated stainless steel corrosion‑resistant lifting bracket, compatible with both circular and rectangular manholes and channels.
2. Can be paired with MXT03 series telemetry terminals to enable wireless data upload, remote parameter configuration, and equipment fault alarms.
3. Supports custom input of cross-section parameters and is compatible with various standard and non-standard ditch and pipe cross-sections.
4. Local high-capacity data storage ensures data persistence even during power outages and supports exporting historical flow curves for traceability.
VI. Summary of Product Value
The MXS05RU radar‑ultrasonic flow meter addresses the operational limitations of conventional standalone radar and submersible Doppler flow meters, balancing measurement accuracy, ease of installation, and long-term maintenance costs. With a single device, it meets the flow‑monitoring needs across diverse settings—urban pipe networks, rivers, and discharge outlets—providing stable, reliable flow data to support urban drainage management, total wastewater volume control, flood‑prevention early warning, and water‑environment assessment.
