Introduction
Soil moisture evaporation measuring instruments, there are currently hydraulic soil evaporators and weighing soil evaporators in China: hydraulic evaporator
Based on the principle of influent buoyancy weighing, the undisturbed soil column to be measured is filled in the evaporator, and then placed on the floating boat floating in the pool:
It forms a floating system: When the water column moisture increases or decreases, the weight changes, and the depth of the evaporator sinking in the pool also changes vertically:
change: The weighing type soil evaporator is determined by weighing a certain volume of soil in its natural state and changing its weight within a certain time interval:
An instrument for measuring soil evaporation: GB/T 41184 "Soil Moisture Evaporation Measuring Instrument" is proposed to consist of two parts:
--- Part 1: Hydraulic evaporators;
--- Part 2: Weighing evaporators:
Soil water evaporation measurement is to study the whole process of soil water and gas cycle and plant emission, and to study the atmosphere-water-plant-soil (SPAC)
Comprehensive system, to explore the law of land surface water balance, for water resources calculation, flood control, production and confluence, hydrological forecast, large-scale project water resources demonstration, river channel
Provide technical support for flood control impact assessment and flood control and drought relief of construction projects within the scope, so as to solve surface water problems through evaporation in areas without data
Provide scientific basis for water resource calculation problem:

4 Product structure and reliability
4:1 Product Structure
The hydraulic evaporator consists of a water tank system (large water tank, top plug, small water tank, etc:), an evaporation system (floating ring, evaporation outer barrel, evaporation inner barrel, size flat
Weighing weights, rain dividers, etc:), collecting systems (pumping conduits, overflow conduits, collecting buckets, collecting outer buckets, seepage buckets, etc:) and measuring systems (micrometers, gauges, etc:)
It is composed of four major parts, such as counter, float, balance weight, etc: The schematic diagram of its structure is shown in Figure 1:
