Rainfall and Water Level Monitoring Instrument - Automatic Observation Facility for Rainfall and Water Level

The rainfall and water level monitoring device JC-SW2 is an extremely important automatic rainfall and water level observation facility. It mainly consists of high-precision rainfall sensors and water level sensors. Rainfall sensor can keenly sense rainfall intensity and rainfall, and can accurately measure whether it is drizzling or rainstorm pouring. Its advanced sensing technology can effectively avoid external interference and ensure data accuracy. The water level sensor monitors the water level changes of Rivers and Lakes, reservoirs and dams in real time, and accurately measures the water level height through sound wave or pressure and other principles. This monitor has automated data collection and transmission functions, which can quickly transmit the collected rainfall and water level data to relevant monitoring platforms or management centers through the network. This enables water conservancy departments, meteorological departments, and others to timely grasp the dynamics of water conditions, providing key basis for flood warning, water resource management, and water conservancy project scheduling, ensuring the safety of people's lives and property and the rational utilization of water resources.
