1. Product Introduction

The ST-URG Ultrasonic Digital Rain Gauge offers stable data and high precision, with an accuracy of up to 0.1mm, making it an ideal device for automatic remote rainfall measurement in meteorological and hydrological monitoring systems. This product consists of a rain collector, rain barrel, measurement subsystem, and cleaning subsystem. It features a weather-resistant material housing with high strength and corrosion resistance, allowing for direct installation in the field. Designed with low power consumption, the static current is only 1.5mA, and it can be powered by solar energy and batteries in outdoor environments. With a short measurement time, a single measurement can be completed within 2 seconds, and the measurement frequency can reach once per minute, enhancing data real-time performance. The entire rain gauge has no mechanical transmission parts, extending its service life and meeting the requirements for large range, high precision, and resistance to harsh environments.
