The tipping bucket rain gauge is an important instrument measuring precipitation quantity or the volume of water from rainfall during an episode.
The height of the water level, expressed in millimeters, indicates the quantity of precipitation per square meter.
The rain gauge can be heated (for snow) or not.
This sensor has applications in winter viability, agriculture, and airports.
Many types of rain gauges can be installed depending on the desired precision and the use environment. METEO OMNIUM adapts the type of sensor to install according to each situation.

The reception cone must be cleaned regularly (twice yearly). Dust, debris, or leaves must be removed from the cone and if necessary, the buckets.
The cable must be checked periodically as well as the sensor's calibration to ensure measurement precision.
Precipitation measurement is relative to the rain gauge's positioning.
It's preferable to select a site protected from wind shears and crosswinds.
As much as possible, we must avoid sites where the rain gauge risks being clogged by leaves or various debris.
