Multi-band Doppler Radar Flow Meter Overview

The multi-band Doppler radar flow meter, independently developed and innovated by Ecolor, is a non-contact fluid flow measurement device that integrates a liquid level gauge, a flow meter and a high-resolution camera into one compact unit. Adopting proprietary multi-band radar frequency shift technology, the Doppler radar flow meter performs continuous data sampling based on the Doppler principle and relies on the SITUMAN Water Conservancy COSP Model to calculate the water level, flow velocity and flow rate parameters of the measured fluid accurately. The built-in camera provides real-time feedback on on-site working conditions, addressing the industry-wide pain point of focusing solely on data while ignoring on-site situations. With IP68 protection, simple non-contact installation and expandable water quality monitoring, this Doppler radar flow meter serves urban underground pipe network monitoring, ecological flow monitoring and smart agriculture monitoring.

Working Principle of the Doppler Radar Flow Meter

The Doppler radar flow meter transmits radar signals toward the water surface and evaluates the signals reflected from the moving flow. Based on the Doppler principle, the frequency shift of the reflected signal is related to the motion of the water, and the proprietary multi-band radar frequency shift technology enables continuous data sampling across multiple bands for robust, ongoing detection. The SITUMAN Water Conservancy COSP hydraulic model then processes the sampled data to accurately calculate the water level, flow velocity and flow rate of the measured fluid, so one device delivers all three parameters at the same time. Because the measurement is completely non-contact, the Doppler radar flow meter stays clear of the water, sediment and debris inside the well, and its operation remains immune to interference caused by dirt accumulation at the well bottom. The integrated camera complements the radar data with visual evidence of actual site conditions whenever it is needed.

Key Features of the Multi-band Doppler Radar Flow Meter

The multi-band Doppler radar flow meter offers ultra-high integration for all-in-one monitoring, easy installation and convenient operation and maintenance:

  • 3-in-1 integration of liquid level gauge, flow meter and camera in a single unit, simplifying system design and data acquisition.
  • High-resolution capture capability; users can customize the daily shooting frequency via the background system and initiate real-time capture of on-site scenarios whenever necessary.
  • A built-in motor allows flexible adjustment of the radar irradiation angle to ensure optimal detection and make device commissioning simple and easy.
  • Stable operation: the device remains free from obstruction by dirt at the bottom of the well, ensuring high working reliability.
  • Compatible with external water quality sensors, enabling the expansion of water quality monitoring capability.
  • Protection class of IP68 for reliable operation in harsh underground environments.

Applications of the Doppler Radar Flow Meter

The Doppler radar flow meter is mainly applicable to urban underground pipe network monitoring, where it measures water level, flow velocity and flow rate in manholes and pipe sections without any contact with the medium. It is equally suited to ecological flow monitoring, helping authorities supervise river and channel flows, and to smart agriculture monitoring, where irrigation and drainage channels need continuous fluid measurement and supervision. These scenarios can all meet the fluid measurement and supervision needs of different fields with one device platform. The combination of radar measurement and on-site photography lets operators verify actual working conditions remotely, which is valuable in locations that are difficult or unsafe to visit regularly, and the high-resolution capture capability preserves a clear visual record of each site. Because the multi-band Doppler radar flow meter can also connect external water quality sensors, a single installation can grow from basic flow monitoring into a more complete monitoring point for pipe networks and open channels.

Installation and Maintenance of the Radar Flow Meter

Installation of the Doppler radar flow meter requires only one set of poles and expansion bolts. Personnel mount the bracket on the well wall and hang the device from above without going down into the well, so the water flow and toxic gases at the bottom of the well have almost no impact on installation. The work takes a short time and causes little impact on on-site traffic or the surrounding environment. During commissioning, the built-in motor makes adjustment of the radar irradiation angle simple and easy, ensuring optimal detection. For operation and maintenance, abnormal conditions can be checked in real time through the camera to view on-site status, and if the device malfunctions it can be replaced easily without personnel going down the well, keeping long-term maintenance effort low.

What is non-contact radar flow monitoring and why is it ideal for sewer applications?
View Answer
<p>Non-contact radar flow monitoring uses radar sensors mounted above the flow to measure surface velocity and water level, calculating flow rate without contacting the wastewater.
