Changes at the gauge.
Radar or a pressure sensor measures water level. Rainfall adds context for the catchment; discharge needs suitable measurements or a calibrated relationship.
Flood early warning
Detect rising water levels early. Measure water level and rainfall continuously, transmit the data and notify the response team.

From measurement to decisions
Measure. Connect. Understand.
Sensors, data loggers and analysis work together as a system. The equipment is selected for your measurement task and location.
Data from the field.
Logger, power supply and communications are designed together. An additional transmission path can be considered for critical sites.
Reach the right people.
Thresholds and recipients are matched to your operation. Sensormanager provides time series and supports SMS and email notifications.

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.
From the field
Field examples.
Rhine flood-stage 1: gauging inside a retention areaOn a Rhine retention area: sensors directly in the riverbed, cabling underground to a higher-mounted logger. Antenna and barometric-vent capillary above the maximum water level — the Aquatos Web can be fully submerged and still streams real-time data.
More than a staff gauge — modern flood monitoringStaff gauges alone aren't enough — we install them with an Aquatos Web logger inside a protective tube. Even three metres high, on bridges or free-standing in overflow basins — with a cabled sensor to a deck-mounted logger in extreme cases.
