2D přesný ultrazvukový anemometr

  • Highly accurate ultrasonic anemometer with RS485 output compatible with FIEDLER recording units
  • Robust design of the device without moving parts
  • High measurement accuracy given by optimized aerodynamic design of ultrasonic sensors
  • Supply voltage in a wide range of 9 to 36 VDC
  • Variant design with outputs RS422, 0..10V, 4-20 mA, CAN, ...

Optimized design

The design of the mechanical design of the ultrasonic anemometer was also made with the help of SW simulation. As a result, turbulence occurring on ultrasonic transducers was minimized.

Sonic anemometr

Reducing turbulence to a minimum resulted in a maximum increase in the accuracy of wind speed and direction measurements.

Application

- Professional weather stations

- Intelligent building management (heating, clinization, ventilation, ...)

- Industrial buildings and security of building structures

- Science and research - environmental monitoring
