The technology exchange meeting for evaporation sensors was held in Weifang

Recently, a technology exchange meeting for the evaporation sensor developed by Shandong Tianhe Environmental Technology Co., Ltd. was held in Weifang. At the meeting, many industry professionals and customer friends arrived at the scene. After understanding, everyone highly affirmed and fully recognized the product. The evaporation sensor is an instrument specifically designed to measure the rate of water evaporation on the surface of liquids or gases. Its core function is to accurately monitor changes in evaporation and provide critical data support for multiple fields. Based on the principles of thermal equilibrium or conservation of mass in physics, the evaporation rate is indirectly reflected by measuring the amount of water transferred from the surface of a liquid or solid to the air during a certain period of time. The specific implementation method includes: the weighing method calculates the evaporation rate by accurately measuring the mass change of the water container over a period of time, with high accuracy but limited by the size of the container and the accuracy of the weighing equipment.

At the meeting, Manager Yu from Tianhe Environmental Technology Co., Ltd. introduced that the main types of small evaporators are filled with a certain amount of clean water daily, and the remaining water is measured by a measuring cup 24 hours later. The reduced amount is the evaporation rate. The large evaporator has a cylindrical barrel with a mouth area of 0.3m ², and a straight pipe is installed at the center of the barrel bottom. The upper end of the straight pipe has a measuring needle seat and a water level indicator needle. The barrel is buried in the ground, and the barrel mouth is slightly higher than the ground. The evaporation rate is calculated by observing the change in water level height at 20:00 every day. A circular vessel with a diameter of 20cm and a depth of 10cm is used for evaporating dishes. A 2cm deep water layer is added daily, and the remaining water depth is measured by pouring out a residual water cup at night. Subtracting the remaining water depth from 20cm is the daily evaporation rate.

Application field

Meteorological observation, as the core component of meteorological and rainfall stations, accurately measures surface evaporation of water and soil, providing data support for understanding climate change, predicting weather patterns, and evaluating water resource conditions. Real time monitoring of changes in farmland evaporation for agricultural irrigation, assisting in the development of scientific irrigation plans, improving water resource utilization efficiency, reducing waste, improving soil structure, and enhancing crop yield and quality. Monitoring the evaporation of water bodies such as lakes, rivers, and reservoirs in water resource management, evaluating the dynamic changes of water resources, and providing data support for water resource allocation, protection, and utilization, is of great significance, especially in arid areas. Environmental protection monitoring of changes in ecosystem evaporation in wetlands, lakes, and other areas, and assessment of ecological health status; Study the impact of industrial emissions and urban heat island effect on evaporation, and provide a basis for environmental policy formulation. Research and education support research in fields such as meteorology, hydrology, and ecology, exploring natural laws and the impact of human activities; As a teaching tool, it helps students understand natural phenomena such as water cycle and climate change.

Advantages and Features

The high-precision measurement response time is less than 1 second, meeting the requirements for data accuracy in multiple fields. Strong environmental adaptability, using stainless steel material for corrosion prevention, double-layer design to prevent direct sunlight errors, and can adapt to various environmental measurements. The high degree of automation supports the use of automatic water adding devices, data collection and transmission devices, etc., to achieve automatic monitoring of the evaporation process and remote transmission of data. As a digital sensor with reliable stability, there is no problem of temperature drift or time drift, and it can maintain stable performance for a long time. The integration of technology with the Internet of Things, big data, artificial intelligence, and other technologies enables more accurate and intelligent irrigation decision-making and management. With the in-depth study of crop growth patterns and irrigation requirements, precision agriculture irrigation models will continue to be optimized, and evaporation sensors will play a more important role in model construction. The policy support for the country's emphasis on sustainable agricultural development will promote the application of advanced equipment such as evaporation sensors, and relevant departments will strengthen standardization construction and technology promotion.
