4310 Precise ultrasonic anemometer

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
