The QYL-R05 radar level transmitters are a high-precision, low-power product that can be used for non-contact liquid level measurement in scenarios such as surface water and underground pipe networks.

These radar level transmitters use pulse coherent radar (PCR) technology with a 60 GHz millimeter-wave signal, achieving millimeter-level accuracy through advanced signal recognition algorithms. This low-power, non-contact measurement is unaffected by temperature, humidity, pressure, dust, water pollutants, or sediments. An optimized wave-suppression filter ensures more accurate and stable measurements.

The mobile APP is connected wirelessly via Bluetooth, making it convenient for on-site debugging and maintenance.

  • IP68 fully waterproof design;
  • Millimeter high-precision liquid level measurement, ultra-low blind area;
  • Power supply circuit anti-reverse connection and lightning strike protection design;
  • Multiple working modes: periodic, dormant, automatic;
  • Lightweight,  compact structure, and simple installation;
  • The mobile APP is connected wirelessly via Bluetooth, making it convenient for on-site debugging and maintenance.
