Automatic Open Pan Evaporation System

Automatic Open Pan Evaporation System with Rain Gauge & Wind Speed Sensor Balaji Hydromet Automatic Open Pan Evaporation System is a precision-engineered solution designed for accurate evaporation measurement in meteorological, agricultural, hydrological, and environmental research applications. Built with an industrial-grade microcontroller-based datalogger, the system ensures reliable performance, high accuracy, and continuous operation even in harsh outdoor weather conditions. This advanced evaporation monitoring system is equipped with a water level measurement range of 0–200 mm and is specially designed to help users observe and manage evaporation loss efficiently. The system allows timely refilling of the pan before complete water depletion, ensuring uninterrupted monitoring and dependable data collection. To improve the quality and usefulness of evaporation analysis, the system can also be integrated with a wind speed sensor and rain gauge sensor. These parameters play an important role in open pan evaporation studies. Wind speed directly affects the rate of evaporation by increasing the movement of air over the water surface, which accelerates moisture loss. Rainfall also has a direct influence on pan water level and evaporation readings, making rain measurement essential for accurate interpretation of collected data. By monitoring these additional weather parameters, the system provides more meaningful and scientifically useful evaporation data for research and field applications. The Balaji Hydromet Automatic Open Pan Evaporation System is an ideal choice for weather stations, agricultural universities, irrigation departments, climate monitoring projects, research institutions, and hydrological studies, where precise evaporation measurement and weather-based analysis are essential.
