Precision sea-level monitoring, built for the coast

The SpaceEcho tide gauge is a web-connected sea-level monitoring station for ports, harbors and coastal research sites. Radar and submersible piezometric sensors run in parallel for cross-validated readings, a dedicated acoustic sensor tracks surface waves, and a custom stilling-well and intake geometry removes the environmental noise that degrades ordinary tide gauges.

What it measures

Sea level and tide height: Redundant radar and submersible piezometric pressure sensing, cross-checked continuously.
Surface-wave activity: A dedicated acoustic (ultrasonic) sensor resolves wave behaviour alongside the tidal signal.
Meteorological suite (Multi-Task Pro): Wind speed and direction, temperature, humidity, pressure, solar radiation, UV and precipitation.
Station health: Connectivity, power status, charging state, network signal and storage, streamed with the environmental data.

A symmetrical double-cone orifice intake acts as a hydrodynamic front-end filter, offsetting currents, waves, vessel wakes and marine fouling before they reach the sensor.

In the field

SpaceEcho tide stations are deployed along Egypt's Mediterranean coast, including Port Said, for NIOF and NRIAG.

Case study Mediterranean tide stations (for NIOF/NRIAG) Tide and current monitoring stations on Egypt's Mediterranean coast for NIOF and NRIAG. Each station measures sea level three ways at once — acoustic, radar and submersible pressure — through an intake built to cancel waves, wakes and currents. Multi-Task Pro stations add a full weather suite. Learn more
