The OTT Pluvio² L is an all-weather precipitation gauge that uses superior weight-based technology to measure the amount and intensity of rain, snow, and hail. Developed in conjunction with industry-leading meteorological services, the OTT Pluvio² L employs a high-precision load cell and algorithms that compensate for wind, temperature, and evaporation, ensuring the highest accuracy precipitation measurements over time.

  • Parameters measured: Cumulative precipitation, precipitation intensity, bucket content in real time and non real time
  • Measurement technology: Weighing principle
  • Product Highlights: All-weather precipitation gauge without moving parts according to WMO guide line No. 8
  • Interface: SDI-12 / RS-485, pulse

  • Accurate measurement: precipitation accuracy within 0.004 inches with accumulation and intensity readings and filter algorithms to compensate for wind, temperature, and evaporation
  • Virtually maintenance-free operation: lifetime factory calibration, drift-free measurements, and robust protective housing eliminate field visits for instrument service
  • Multiple communication interfaces: SDI-12, RS-485, and Pulse Output options
  • Solar panel power options make the instrument ideal for remote locations
  • Easy software setup and a USB interface for communication with computer
  • Wind protection shield available for particularly exposed locations
  • Heated ring option available to prevent the accumulation of snow on the sensor
  • Easy installation onto 4' pipes

  • Precipitation Measurement:  Continuous, real-time measurement of rain, snow, hail, and sleet in all monitoring environments, even remote environments without power supply
  • Early Flood Warning: when combined with water level sensors, the Pluvio² L is the central component in an early flood warning system
  • Urban hydrology: Even in the event of heavy rainfall of up to 3000 mm/h the Pluvio² L provides precise intensity values for controlling stormwater runoff to the sewer system.
