Meet the Pressure Wave Gauge PTM
Pressure sensors are a popular instrument for nearshore wave measurements. Obscape’s Pressure-based Wave Gauge PTM adds real-time data transfer and solar power into the mix, providing a very complete and convenient package for wave observations.
With the pressure sensor mounted below the water surface and the data logger above, real-time wave observations in a harbour basin, at an offshore platform or at a shore-based pier or jetty become very convenient. Whether you are interested in improving navigational safety or wish to investigate the impact of waves on coastal morphology, Obscape’s Pressure-based Wave Gauge PTM suits your needs.
Wave monitoring plays an important role in various fields of science and industry. The Wave Gauge is suitable for application whenever a fixed structure is available to mount the device to. This can either be a platform, pier, jetty, pole, bridge deck, etc.
The instrument measures the wave-induced water pressure using an industry-grade pressure sensor. Internal processing algorithms based on linear wave theory will convert the pressure timeseries into non-directional wave spectra and bulk wave parameters.
