Key features


  • Measuring wind direction and speed insusceptibly to bird nesting thanks to roofed construction
  • Built-in data pre-processing, universal interfaces and selectable output protocols
  • Maintenance-free operation – no moving parts that can wear out
  • Compatible with many commercially available Met/HydroMet data loggers and PLS systems thanks to an open communication protocol
  • Suitable for all climate zones; also for solar-powered automatic meteorological stations


The WS200-UMB Compact Weather Station for measuring of wind direction and wind speed. Ultrasonic sensor technology is used to take wind measurements. Measurement output can be accessed by the following protocols: UMB-Binary, UMB-ASCII, SDI-12, MODBUS.
