The accurate recording of water levels is often a requirement either on its own or alongside other measurements or activities.
This may be for short-term deployments during bathymetric surveys for example, or longer-term monitoring for environmental studies of inland waterways.
The Hydrosphere ‘HydroTide’ pressure sensor and logger pictured below is the instrument of choice at jetty installations.
Alternatively, the Coastal Leasing ‘MacroTide’ autonomous pressure sensor and logger shown below can be deployed either offshore in a seabed frame, or in a tidal estuary or inland waterway for several months at a time.
Supplementary board/step gauges surveyed into the required height datum are often employed to calibrate the recording instruments.
