OMC-7018 Data Buoy

The OMC-7018 is a 1.8 m diameter buoy for measuring water quality, water current and meteorological parameters. It can be used in open sea, in coastal areas, in harbours or even in large lakes. Applications can range from short term monitoring for supporting marine engineering projects, to long term monitoring for vessel guidance, harbour operations, flood protection or environmental studies.

One platform, modular payload
The basic platform of the OMC-7018 is a yellow polyethylene float with a diameter of 1.8 m and an instrument tower on top. Based on the user requirements, a modular payload of sensors, data processing, communications and power supply is added. These modules are common to all Observator OMC-70xx buoys. The modular approach allows the user to select only the components he needs.
