RQA rain quantity analyzer

RQA rain quantity analyzer

Measurements of relative intensity of precipitation, present liquid or solid precipitation

The RQA Sensor is designed to accurately measure the relative intensity of precipitation and detect the type of precipitation present, whether liquid or solid. Using advanced sensing technology, the RQA provides reliable, real-time data on rainfall, snow, sleet, or mixed precipitation, making it ideal for meteorological monitoring and environmental applications.

Key features

  • Measurements of relative intensity of precipitation, present liquid or solid precipitation, rain duration
  • Elimination of temperature changes, dirt on the sensing element
  • Preheat for eliminate condensation and prevent the detection of false precipitation
  • Automatic calibration
  • Output signals logical 0/1, RS485, SDI-12, ModBus
  • Easy maintenance
  • Long-term stability
  • All parameters are user-configurable
  • Industrial design
  • Low power consumption
  • Wide-range voltage supply
  • Adjustable heating
