The project deploys Huaju Scientific Instruments’ mud level gauges, which utilize Frequency Modulated Continuous Wave (FMCW) radar technology to measure mud and water levels. This energy-efficient, non-contact method ensures accuracy and stability unaffected by environmental factors.

In mid-to-late June 2021 (pre-flood season), a field survey was conducted in southeastern Tibet as part of a national scientific research project led by Beijing Normal University under the Ministry of Science and Technology. Utilizing patented handheld radar flowmeters (RD-60) and outdoor rangefinders developed by Shenzhen Huaju Scientific Instruments Co., Ltd., the project team surveyed 85 rivers (including tributaries) in the region. This effort generated a dataset comprising 141 measurement points, capturing critical pre-flood environmental conditions for flood risk analysis in southeastern Tibet.
