ESMYL100/200/300/400 RS485 or pulse output Stainless steel tipping bucket rain gauge

ESMYL100/200/300/400 tipping bucket rain gauge is a device used to measure liquid precipitation, rainfall intensity, and the start and end times of precipitation. It is widely used in meteorological monitoring and forecasting, hydrology and water resources management, agricultural and ecological research, disaster warning and emergency response, scientific research, and educational experiments, providing critical data support for weather forecasting, flood warnings, and irrigation planning.

Typical Application Scenarios
1. Meteorological / Hydrological Stations: National-level rainfall observation
2. Water Conservancy / Reservoirs: Watershed rainfall, flood control scheduling
3. Geological Hazards: Flash floods, landslides, debris flow warning
4. Agriculture and Forestry: Irrigation decisions, soil moisture monitoring
5. Smart Cities: Road water accumulation, drainage monitoring
6. Marine / Coastal: High-salinity fog environment (choose 316)

product details

PRODUCT DESCRIPTION

Rainwater enters the rain gauge through the topmost water inlet, falls into the water collection slot, and flows into the tipping bucket through the funnel. When the water accumulates to a certain height (for example, 0.2mm), the tipping bucket loses balance and tips over. Each time the tipping bucket tips, the switch completes the circuit and outputs a pulse signal. By measuring the pulse signals, the amount of rainfall can be determined.

Product Features

Accurate measurements and reliable data
Simple structure and low maintenance costs
