Summary:
Evaporation sensor is used to sense the change of water evaporation sensor, can observe the change rule of water evaporation in different time, suitable for meteorological observation, plant cultivation, seed cultivation, agriculture and forestry, geological survey, scientific research and other fields. Can be used with data acquisition sending device and other supporting, evaporation process automatic monitoring, also can be combined with data collection and storage device (recorder), evaporation data of automatic storage, also be sent with the rainfall sensor, data acquisition device collocation is used, such as evaporation, rainfall process of automatic observation and remote transmission. In addition, it can be used as a component of rain measuring station, evaporation station, weather station, environmental monitoring station and other equipment to observe “water surface evaporation”, one of the meteorological or environmental parameters.
Introduction to evaporation and evaporation:
The process by which water changes from liquid or solid into gas and escapes into the atmosphere is called evaporation. Evaporation is the amount of water dispersed into the air by evaporation over a given period of time, usually expressed in millimeters of the thickness of the evaporated water layer, the amount of water evaporation from the water surface or soil.
The influence of evaporation on people mainly focuses on agricultural production and life. The study of evaporation change is very important for understanding climate change and discussing the law of water cycle change. In practice, it has important guiding significance for water conservancy project design, soil improvement of agriculture, forestry and animal husbandry, soil moisture regulation, irrigation quota formulation, water resources research, climate regionalization and so on.
Significance of evaporation research:
The study of evaporation change is of great significance for understanding climate change and exploring the law of water cycle change. And evaporation sensors are essential in any advanced irrigation system to prevent continuous irrigation under adverse weather conditions such as wind, rain or sufficiently wet soil, so as to achieve intelligent management.
In practice, it has important guiding significance for water conservancy project design, soil improvement of agriculture, forestry and animal husbandry, soil moisture regulation, irrigation quota formulation, water resources research, climate regionalization and so on.
Working principle:
Evaporation sensor adopts pressure measurement principle, by measuring the change of liquid weight in the evaporation dish, and then calculate the height of the page, so as to measure evaporation. Evaporation sensor can adapt to all kinds of environment of water evaporation measurement, not affected by liquid freezing, overcome the use of ultrasonic principle when measuring liquid level height is not accurate measurement, no water damage sensor, low accuracy of measurement.
In agriculture, if irrigation is the income item of farmland water balance, evaporation is the main expenditure item of water balance, it is an important basis for planning water storage and water supply, designing drought prevention and anti-drought measures, and an important index to identify the water supply conditions of crops. Water evaporation affects cropping systems, cultivation practices and crop growth. Understand local water evaporation through evaporation sensor, improve water utilization rate through data, timely water replenishment or stop irrigation, and provide guarantee for crop growth.
