产品概述
SS103U-01 is an ultrasonic wind speed and wind direction measuring instrument developed on the basis of the ultrasonic principle.
It calculates wind speed and wind direction by measuring the time difference of transmitted and received ultrasonic pulses. The sensor can measure instantaneous wind speed and wind direction simultaneously and supports RS485 output.
