Weighing rain gauge with automatic drain

Like all rain[e]-series rain gauges, the rain[e]314 uses a sensitive measuring principle and fulfills all requirements of WMO Guideline No. 8. Real-time measured values for quantity and intensity of all liquid precipitation in the range of 0...720 mm/h will be output accurately and reliably. The rain[e]314 has a compact, robust design, with state-of-the-art weighing technology inside. Fully automatic continuous emptying prevents overflow and incorrect measurements and enables maintenance-free long-term use even under extreme weather conditions.   

  • real-time output of precipitation intensity, amount and total amount parameters
  • measurement of each drop with the amazing resolution of 0.001 mm/m2
  • compact design with enlarged 314 cm2 collecting area
  • best connectivity by diverse interfaces for simple system integration
  • version with highly efficient heating for low power consumption
  • easy calibration using a reference weight

to reduce the measurement error due to wind influence.

In combination with the weighing precipitation sensor rain[e]H3, the Tretjakov windshield is used by the German Weather Service (DWD) at selected locations.

The windshield is equipped with vertically circularly arranged stainless steel blades. These segments are horizontally movable and are conically joined at the base of the precipitation sensor.

The Tretjakov windshield consists of a frame, metal segments and accessories for quick and easy installation.
