Measurement Based on Ultrasonic

 AR200-H uses ultrasonic to determine wind speed and direction. The measurement is based on transit time, the time it takes for the ultrasound to travel from one transducer to another, depending on the wind speed.

The wind measurement is calculated in a way that completely eliminates the effects of altitude, temperature and humidity.


High accuracy and free-maintenance


It has no moving parts, and it is resistant to contamination and corrosion.

It measures accurately and produces reliable data in demanding wind conditions and climates without periodic or on-demand maintenance.

Configurable data output

Analog signal output support voltage and current output optional;

Digital signal output support ASCII and MODBUS communication protocol, or customize
