Model recommendation: TH-YL4Manufacturer of meteorological and environmental monitoring instruments and equipment, Yunjing Tianhe supports customized services for merchants. Choose Shandong Yunjing Tianhe for equipment, and rest assured. Use of radar rainfall sensors - real-time monitoring of water depth and rainfall intensity to assist in emergency drainage decision-makingRadar rainfall sensor is a high-precision, non-contact precipitation monitoring device based on Doppler radar wave technology. By emitting electromagnetic beams of specific frequencies and receiving echo signals reflected by raindrops, it achieves real-time and continuous monitoring of rainfall intensity, type, and spatial distribution. There is no need to contact raindrops directly, avoiding mechanical wear and external physical interference Meteorological monitoring and disaster warning provide meteorological departments with real-time and accurate rainfall data, help forecasters more accurately predict the occurrence, development and movement path of rainstorm, and timely release early warning information. Plays a key role in monitoring urban waterlogging, warning of landslides in mountainous valleys, and recording rainfall during typhoon landings in coastal areas. Real time monitoring of water level, flow rate, velocity and other parameters of rivers, reservoirs, lakes and other water bodies in hydrological research and water resource management, providing data support for hydrological research and water resource management. Help the water conservancy department better understand the distribution and changes of water resources, optimize water resource allocation, and improve water resource utilization efficiency. This greatly reduces maintenance requirements and the risk of data loss due to factors such as leaf cover, evaporation loss, and sediment blockage.

Product Introduction
YL4 adopts a small flat panel radar module internally, using 24GHz Doppler radar wave technology to measure the falling speed of rainfall droplets, and can distinguish the types of rain, snow, hail and the intensity of rainfall based on the particle size and falling speed of precipitation droplets. The YL4 radar rainfall detector is more sensitive and quickly detects the start and end time of rainfall than traditional mechanical rainfall detection methods, and there is no need to worry about objects such as leaves covering the detector surface affecting rainfall detection, nor is there a need for heating devices to prevent icing. The YL4 detector has no moving parts inside, is almost maintenance free, and has a small size with extremely low energy consumption.
