Buoy - TriOS Mess- und Datentechnik

Go to content

TriOS Buoy-175 is a modern state-of-the-art instrumentation platform for environmental monitoring of water quality in small lakes, reservoirs or rivers. Flexibility, robustness, easy servicing access and protection for vandalism have been the main driving forces during the development of Buoy-175.

A large technical compartment contains batteries, controller, cables, etc. It is connected inside the Buoy -175 to the easy accessible Sensor Sections. The Sensor Sections are 4 locked build –in Moon Pools in the buoy that protect the sensors and measuring instruments.

The system is supplied with a range of sensors that can specified by the customer. All buoys are fitted with solar panels and batteries. An airblast cleaning system used on many TriOS sensors, Navigation/warning lights and other markings together with telemetry options are available, selected to suit both the location and application requirements.

Each of the 4 sensor frames can hold up to four sensors and is completely adaptable to any applications needs.

Possible options:
  • Data Controller
  • Airblast system
  • Topmarks (e.g. St. Andrews Cross)
  • Marine lantern
  • Weather station/Meteorological sensor package
  • Telemetry
  • Expandable battery pack from 2 to 8 cells
