In order to carry out this 6-week campaign, SEMERU clearly decided to go for the DTU2 standalone PLC connected to the 3G/2G network and open to all types of sensors (velocity/doppler, rain gauge, level radar sensor, etc.)
The implementation was effective in 3 phases, depending on the watershed. The measurement points were spread over the different flow standard:
- Wastewater & rainwater harvesting
- Storm drain,
- Pumping station.
On a daily basis, SEMERU hydraulic engineers were able to gather, verify and validate all data from all measurement chains in complete autonomy, reducing the complexity due to the accessibility of some operating sites.
In addition to height, velocity and flow, information on “signal quality”, “gain”, “temperature” and “signal strength” helped the engineers to qualify the results during the campaign.
