Description

MAIN FEATURES 

The RG rain gauges series are tipping bucket sensors for the continuous measurement of liquid or solid atmospheric precipitation. The sensor is available with a funnel collection area of 200 or 400 cm2. It’s entirely built with corrosion-resistant materials to ensure a long life, reliability and robustness.

The tipping bucket system is housed within a sealed compartment that protects it from dirty and insects. The sealed compartment is fixed on a basement platform, moreover includes 2 mounting holes to drain the measured rain and three adjustment screws for rain gauge leveling by a bubble level.

The funnel rain collector, has an internal shaping debounce that meets the guidelines of the WMO – World Meteorological Organization, it’s treated with special non-stick coatings to ensure optimal flow of the rain precipitated. 

The bottom of the funnel is equipped with two filters to prevent that debris could ends into the tipping bucket system and stuff it.

• The first filter is constituted by a removable device that retains the larger depositions such as leaves, twigs, solids precipitated, preventing these elements could block the opening hole that brings water to the measurement system.
• The second filter is a overflow system that retains the small and dusty depositions and conveys the perfectly clean water in to the tipping bucket measurement system, avoiding in this way sediment deposition that may alter the tilting balance ensuring the correctness of the measurement.

Reached the set level, the bucket under the action of its own weight, rotates draining the rain. During the rotation, the normally open reed contact closes generating an electrical pulse. The precipitation measurement is based on the number of bucket emptying cycles. The reed contacts closes at the time of rotation between one section and the other. The number of pulses can be detected and recorded by the data logger mod. mMET1-2-3 Geoves or by any standard pulse counter.

To ensure an accurate measurement even under low temperature climatic conditions or in case of presence of snowfall, it’s available a heated version which is automatically powered around +4 °C in order to prevent the deposit of snow and icing
