Meet the Wave Module PTM
Highly accurate real-time wave measurement system that reports
the wave spectrum including wave height, wave period and more. By pairing Obscape’s versatile Power & Telemetry Module with our accurate wave sensor, the Obscape Wave Module PTM mounted to most standard hydrography and navigation buoys empowers the customer to accurately measure waves within a low cost and rugged IP68 solution.
The Wave Module PTM uses a combination of motion sensors and an electronic compass to measure the wave field with high accuracy. This yields the non-directional wave spectrum and all parameters that can be derived from it, such as the 1-dimensional energy-density spectrum and a range of bulk wave parameters.
Habour markers, offshore floating hulls and navigational buoys are designed to withstand high shipping traffic areas, extreme swell and current conditions. By mounting the Obscape Wave Module to these types of stable floating structures, the bespoke Obscape engineered wave measurement system offers a rugged IP68, accurate and reliable solution to measure the full wave spectrum.
The Wave Module is suitable for application in ports and harbour entrances, shipping lanes and edge channels, inland Waterways, aquaculture areas and offshore power farms to name a few.
Whether you are interested in Marine & Coastal engineering, Oceanographic research, Environmental monitoring or Work compliance monitoring the Obscape Wave Module suits your needs.
Deployment of the Wave Module can be achieved by mounting to a floating hull structure prior to deployment or onsite at sea. Standard brackets are supplied, or a simple cage fabricated by the customer to enable mounting to most habour markers, offshore floating hulls and navigational buoys
