EML joined forces with the technology-focused Uruguayan company Nettra, to provide a smart autonomous rainfall solution to INUMET, the Uruguayan Meteorological Institute. This system comprises a network of 60 stations distributed throughout Uruguay, located in both urban and rural locations. In November 2018, EML and Nettra are undertaking a joint exhibition in Santiago, Chile, to promote this successful rainfall monitoring solution to other Hydro-Met Institutes in South America. |

Measuring precipitation accurately and getting the right information to the appropriate people quickly is extremely challenging. Some applications, such as real-time flood forecasting, require rapid response between data collection and information dissemination, in order to save lives. The partnership developed between EML and Nettra was created to address these evolving needs of the global Hydro-Met industry, in the context of a changing climate where extreme rainfall events are becoming more frequent and more intense.
As UK manufacturers, EML has been designing and supplying internationally-leading aerodynamic rainfall products for more than 30 years. Nettra specializes in the development and implementation of IoT technologies applied to telemetry and remote control. Through a partnership with the National Uruguayan Meteorological Institute, INUMET, a solution was developed to showcase the many benefits of combining excellent data quality with seamless Smart IoT infrastructures.
EML and Nettra worked together to deliver a network of 60 telemetered automatic rainfall systems, distributed throughout Uruguay. Each station is comprised of an EML SBS rain gauge and an RTU+ from Nettra, which is used to acquire, record and transmit the information provided by the SBS rain gauge. The data are transmitted wirelessly to the INUMET database, where they can be used in real-time decision-making if appropriate, and then archived. All 60 stations are autonomous, they do not require any external power supply other than a solar panel, which recharges the batteries. The images below show a system at a rural site (left) and an urban rooftop site (right). In both cases, the SBS rain gauge is mounted on a pedestal, which has a solar panel attached to it. Also mounted on the pedestal is an enclosure which houses the RTU+ and the power supply.
The rainfall stations shown below transmit the information through cellular network to a Fiware platform using a secure VPN connection. In case of loss of communication, information is stored locally and transmitted once communications are restored. Nettra’s data solution also has the capability to use pattern recognition algorithms, thus analysing data and delivering an important service to customers. This will be an important tool for future developments to the network.
