Recently, Beijing Aozuo Ecological Instrument Co., Ltd. successfully completedThe installation and commissioning work of the "SoilScope Controlled Infiltration Experiment System" in the "National Major Science and Technology Infrastructure for Precision Gravity Measurement" project.

The "Precision Gravity Measurement Research Facility" (PGMF for short) is jointly built by Huazhong University of Science and Technology as the project legal person, Institute of Surveying and Geophysics of the Chinese Academy of Sciences, Institute of Physics and Mathematics of the Chinese Academy of Sciences, China University of Geosciences (Wuhan) and Sun Yat sen University. It mainly builds a precision gravity measurement reference platform and detection system, satellite, aviation and underwater gravity detection environment simulation and physical simulation test systems, and global high-precision gravity field data processing system. The automatic weighing type permeameter (SoilScope controlled type) designed and constructed by our company can provide data support for precise measurement of soil infiltration and evapotranspiration in the hydrological cycle process through a high-precision automatic weighing system, and provide support for the study of hydrological effects caused by local water storage changes in gravity measurement.

Automatic weighing type steam permeameterThere are 2 sets of SoilScope control type, with an area of 1 square meter and heights of 1 meter and 1 meter respectively.5Rice. Each system includes tanks, weighing systems, drainage systems, soil sensors, and data acquisition systems. The system uses backfilled soil and column heightThe experimental soil of the 1-meter tank is residual soil from the southern slope of Yujia Mountain, with a column height of 1.5The experimental soil of the rice tank is the center of gravityThe miscellaneous fill and residual slope deposits in the courtyard of Building B. Evapotranspiration accuracy is 0.1At a depth of mm, the column profile is equipped with four layers of soil moisture, temperature, conductivity, and soil water potential sensors. Equipped with independently developed by an Australian companyENvidia data platform supports remote control.
