    • ADVRDV composite passenger well flowmeter
    Measurement principle
      The product utilizes a composite dual-mode sensor combining radar Doppler and ultrasonic Doppler to detect water flow velocity, while simultaneously monitoring water level variations through the integration of radar, hydrostatic pressure, and conductivity sensors, thereby calculating real-time flow rates in manholes. Designed with low maintenance requirements as a primary objective, this product fully leverages the advantages of non-contact flow measurement via radar in manhole flow monitoring scenarios, reducing the likelihood of sensor fouling. Ultrasonic contact measurement supplements velocity detection during high water levels. The coordinated operation of multiple sensors enables complementary strengths, making the system more adapt
    able to diverse working condition requirements.
     
      This type of sensor is more suitable for use in situations with relatively fast flow rates.
     
     
     
     
     
     
    ◆Main Features
    Dual-mode (ultrasonic and radar wave) flow velocity sensing, seamless (no blind
    zone) docking;
    Note the flow velocity boundary conditions: 0.05m/s~0.2m/s (non-contact radar fl
    ow velocity sensing);
    Unidirectional model (when using ultrasonic speed measurement, flow direction i
    s not recognized, outputting absolute values);
    Bidirectional flow model (identifies positive regurgitation, flow velocity and flow r
    ate carry positive/negative signs);
    Multi-mode water level (radar, static pressure, and conductivity) sensing (built-in
    flow velocity-dynamic pressure compensation);
     
    Output parameters: comprehensive flow velocity, comprehensive flow rate, comprehensive water level;
    Other parameters: single-mode flow velocity, flow rate, water level, status of each sensor;
    Top-mounted installation on horizontal pipes, enabling wellhead operations via brackets;
    Main unit features an alloy-plastic housing with excellent corrosion resistance, waterproofing, and impact
    resistance; potted sealing ensures no impact from temperature variations on sealing;
    Supports RS485 upgrade, enabling remote OTA when paired with the main unit;
    Top-mounted installation on horizontal pipelines effectively prevents sensor material buildup;
    Mounting brackets facilitate easy sensor fixation.
     
    ◆Application scenarios
      Specialized sensor for manhole flow measurement, suitable for remote monitoring of manhole flow velocity, water level, and flow rate
