Tipping Bucket Rain Gauge

Tipping Bucket Rain Gauge

Rain gauge is a device to measure liquid rain fall amount and intensity. The device is composed of a rain collector cone and a double-chamber tipping bucket connected to a magnet. In order to meet the requirement of information transmission, processing, recording and display, amount of rainfall is converted to pulse output by the magnet. It can be widely used in weather stations, hydrometric stations, agriculture & forestry, defence & field monitoring stations. It can provide the original data for flood prevention, water-supply system, and reservoir water management in plant.

Features
  • Compact size for easy use.
  • High accuracy, good stability.
  • Mesh in the funnel preventing debris such as leaves and insects from entering the working of rain sensor (mesh is optional).
  • Highly polished stainless steel construction.
  • Rain collector with filter, to prevent the leaves, such as debris jam over the hole.
  • Optional heating function in cold region.
Applications

Water supply systems, Hydrology, Natural disaster monitoring, Agro-meteorological research, Cimate research, Weather stations etc.
