Flood early warning
Measure autonomously, transmit redundantly, alert early — gauge and rainfall networks for the EU Floods Directive and municipal heavy-rain provision.
What we measure.
Flood early warning stands or falls with data availability during an event. We measure water level W at the gauge, rainfall and — where continuous measurement is possible — discharge Q via the calibrated stage-discharge (W-Q) relationship. The stations run off-grid on solar/battery and transmit redundantly, so values still arrive when the cellular network is congested during an event.
- Water level Wnon-contact via radar or a pressure probe in the gauge chamber
- Rainfalltipping-bucket or weighing gauge via pulse-counter adapter
- Discharge Qfrom level and a calibrated stage-discharge relationship, where feasible
- Threshold alertsSMS and e-mail to the on-call team
- Redundant transmissionLTE-M with NB-IoT fallback, optional second radio path
Methods & standards.
The gauge follows DIN EN ISO 4373, discharge determination the calibrated stage-discharge relationships per ISO 1100. Measurement and transmission intervals are sized to the catchment's required lead time. The stations are standard for implementing the EU Floods Directive and for municipal heavy-rain hazard maps.
