Measuring rainfall levels  

Rainwater measurement data are essential when monitoring the levels of natural bodies of water. This type of data helps with the prevention and management of high water, and can reduce or even prevent the flooding caused by the overflow of water courses. On the other hand, during periods of drought, rainfall data can help operators to anticipate water shortages and take the necessary steps.  

Rainfall has a direct impact on the groundwater tables and surface water levels. Within the water cycle, rainfall levels influence the availability of drinking water previously harvested in these environments.  

Claire Group’s solutions for rainfall measurement

Modular equipment for measurement results tailored to the local context

Ijinus, a specialist in connected measurement devices, produces sensors which monitor the networks throughout the water cycle. The company has developed a self-powered rain gauge, which conforms to regulatory requirements and can measure rainfall levels, monitor continuous infiltration or seepage, overflows and the availability of water resources. Ijinus devices are compact, self-powered and modular. Output measurements can be tailored to the local ground conditions in order to anticipate weather events and their consequences.

people are permanently exposed to the consequences of flooding caused by overflowing water courses, and 16.8 million of them live in mainland France.

Our rainfall monitoring solutions

Innovative solutions for natural waters

Really simple to set up and install, the RG20 or RG25, paired with a datalogger, can be used equally well in temporary or permanent rainfall monitoring programmes. The rain gauge is connected to a logger which records the local data by radio, or on a remote surveillance tool. This ‘tipping bucket’ rain gauge consists of a funnel collector with two calibrated containers designed to prevent the rain from splashing internally or externally, as recommended by the WMO (World Meteorological Organization). The data can be logged either by time stamping the bucket tips, or based on cumulative rainfall, and the device can be programmed to issue alerts.
