High-accuracy precipitation data is used for watershed monitoring, airport and highway transportation forecasts,  general weather forecasting,  and Doppler radar ground truthing.

OTT Hydromet offers a variety of precipitation measurement technologies, including high-accuracy laser disdrometers and weighing bucket gauges that can be paired with multiple telemetry and power options for deployment in remote locations.

Precipitation sensor and rain gauge

OTT Parsivel² - Laser Weather Sensor

Laser precipitation disdrometer measuring all precipitation types

The OTT Parsivel² is a modern laser disdrometer for comprehensive measurement of all precipitation types. The Parsivel² captures both the size and speed of falling particles, classifying them into one of 32 separate size and velocity classes.

  • Precipitation type, intensity, drop size distribution, radar reflectivity
  • Laser optical
  • Simultaneous measurement of 32 classes for particle sizes and velocities
  • SDI-12 / RS-485, pulse

OTT Pluvio² - Weighing Rain Gauge

All-weather, high accuracy rain gauge for continuous data collection

The OTT Pluvio² is an all-weather precipitation gauge that uses superior weight-based technology to measure the amount and intensity of rain, snow, and hail.

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