CEETIDE MAX™

Tide and waves

Two VEGAPULS 80 GHz radar channels record tide and live wave at up to 20 Hz, with GNSS time synchronisation keeping every reading accurately timed.

Ports & harbours

Continuous tide records and live output for port operations and navigation.

Hydrographic survey

Live tide to survey vessels over UHF or cellular, with the station as an RTK base.

Dredging & marine works

Real-time water level for dredge depth control and marine construction sites.

Flood & storm surge monitoring

Live water levels to flood warning and control-room systems, with long-term records for surge studies.

Remote & unattended sites

Solar power and web access, so the station runs for months without a site visit.

Industrial water levels

Interference-tolerant radar gauging for intakes, outfalls and plant sites.

Configure your system

Build your station

Pick your radar sensors, decide on GNSS, then connect the telemetry, power and devices your site needs.

Step 1 · Radar sensors
