Weighing rain gauge Pluvio² L

400 cm²SDI-12with RS-485 interface

Overview
The Ott Pluvio² L is an all-weather weighing precipitation gauge that measures amount and intensity of rain, snow and hail using a high-precision load cell and advanced compensation algorithms. It corrects for wind, temperature and evaporation to deliver reliable precipitation data for meteorology, hydrology and climate monitoring.

Summary
High-precision weighing precipitation sensor providing accurate measurement of liquid and solid precipitation and precipitation intensity. Designed for meteorological stations, hydrological networks, flood warning systems and long-term climate monitoring.

Benefits

• All-weather weighing precipitation gauge (WMO No. 8): Direct weight measurement of collected solid and liquid precipitation; outputs processed data such as intensity and cumulative amount in mm and inch units.
• High accuracy over full intensity range: Sensitive load cell and high-resolution data acquisition with approved algorithms to compensate temperature and wind effects, ensuring accurate data from light drizzle to heavy tropical rain and high data availability (≈99%).
• Factory calibration and high reliability: Individually calibrated, hermetically sealed load cell with factory acceptance test report; long MTBF indicated.
• Intelligent rim-heater modes: Four heater modes (constant rim temperature, time-controlled per NWS, solid-precipitation controlled and temperature-range controlled) supporting mains, solar or battery operation.
• Low total cost of ownership: Virtually maintenance-free design with recommended maintenance/calibration of 1–2 site visits per year; suitable for remote and high-mountain deployments.
• Service and connectivity: Embedded USB port for direct PC connection for configuration, monitoring, firmware updates and guided accuracy checks via the operating software.
