Weighing-Type Water Surface Automatic Evaporator

I. Product Overview

The weighing-type water surface automatic evaporator is an upgraded iteration of traditional evaporation observation instruments. It features high measurement accuracy, easy installation, and a high degree of automation. Key parameters comply with the national standard "Water Surface Evaporation System" (GB/T21327-2007). Equipped with automatic water replenishment and drainage functions, it stably controls the water replenishment level, significantly reducing manual maintenance efforts. It is an ideal replacement product for sectors such as hydrology, meteorology, and power.

II. Working Principle

The weighing-type water surface automatic evaporator uses a high-precision, low-power consumption weighing sensor to detect changes in water weight and calculate evaporation in real time. Even in environments with minimal evaporation, it can monitor and determine the periodic patterns of evaporation.

III. System Composition

The weighing-type water surface evaporator mainly consists of a 20cm evaporation pan, weighing platform, high-precision weighing sensor, field protective housing, data collector, automatic water replenishment and drainage system, data remote transmission module (optional), solar power supply system (optional), and main chassis.
