rainfall measuring equipment Achieves High-Precision Real-Time Precipitation Monitoring Through Mechanical Induction

rainfall measuring equipment has a 200mm diameter drum and uses a mechanical tipping bucket combined with electromagnetic induction to collect rainfall data. It has a resolution of 0.2mm, a measurement error of ≤±2%, supports Modbus 485 output, and can monitor rainfall of varying intensities in environments ranging from 0-50℃.

rainfall measuring equipment, relying on mechanical induction for high-precision real-time precipitation monitoring, is a commonly used automated monitoring device in hydrological and meteorological projects. The overall diameter of the rain-collecting drum is Φ200mm. It employs a mature tipping bucket structure combined with electromagnetic induction elements to collect rainfall data. After rainwater enters the instrument, it flows into two equal-volume measuring chambers on both sides. When the water volume reaches a certain value, the tipping bucket flips, and the magnet synchronously triggers the induction element, generating a corresponding rainfall signal. This cycle continuously monitors rainfall, ultimately converting the physical rainfall data into digital data for output.

The rainfall measuring equipment instrument is adaptable to most outdoor working environments, operating within a temperature range of 0℃ to 50℃. The ambient humidity must be maintained below 95% without condensation to prevent moisture accumulation from affecting the normal operation of internal electronic components. The instrument has a basic resolution of 0.2mm and an overall measurement error of no more than ±2%. It can cover different levels of rainfall conditions, with a standard rainfall intensity monitoring range of 0-4mm/min and a short-duration heavy rainfall intensity range of 0-10mm/min. It also has short-duration extreme rainfall intensity limits of 8mm/min and 15mm/min, enabling it to handle rainfall data collection tasks during heavy rain and reducing data loss issues in heavy rain situations.

The rainfall measuring equipment uses Modbus 485 as its data output method, ensuring strong signal transmission stability. It can directly connect to various data acquisition terminals and monitoring platforms, allowing staff to remotely view real-time rainfall, cumulative rainfall, and other monitoring data without the need for regular on-site manual data readings. Stable data output capability also reduces the difficulty of setting up the entire monitoring system later, facilitating integration with other sensors such as water level and soil moisture sensors to form an integrated monitoring station.

rainfall measuring equipment can be applied in various scenarios such as urban flood control, reservoir hydrological monitoring, agricultural meteorological observation, and outdoor scientific research stations. Regular cleaning of the filter screen and periodic calibration of the tipping bucket's balance will ensure stable measurement accuracy over the long term, providing reliable data support for various precipitation-related monitoring tasks.
