Ultrasonic flow meter (Doppler)

An ultrasonic flow meter (Doppler) is a contact-type intelligent online monitoring device, mainly used for monitoring the flow velocity and flow rate in gravity flow pipe networks, enabling real-time monitoring of flow rate and water level in drainage pipe networks, drainage outlets, and river and lake systems.

Doppler flow meter

  • iconAdvanced dual-beam Doppler detection technology

    Based on the dual-beam Doppler principle, water flow velocity and water level are simultaneously measured, and instantaneous flow rate is calculated using a hydraulic model.

  • iconPrecise perception

    For minute changes in ambient temperature of ±0.2°C, precise digital temperature compensation technology is used for more accurate measurements.

  • iconSpecial design for sensor aviation connector

    The screw-type locking mechanism provides waterproof and corrosion-resistant protection, ensuring reliability, durability, and minimal maintenance.

  • iconCharging/battery swapping optional design

    Adaptable to diverse needs under different operating conditions; ultra-low power consumption design for longer battery life; also equipped with a low battery warning function, which intelligently reduces the communication frequency after a low battery warning to extend battery life.

  • iconMinute-level measurement

    The communication frequency is intelligently adjusted, automatically changing between 15 minutes, 5 minutes, and 2 minutes based on the water level warning threshold, and the frequency can also be customized.
