Ultrasonic Anemometer
Voltage Inputs
Model 81000VRE
The VRE model has an extended mast that separates the transducer array from the instrument body. Each sensor is individually wind-tunnel calibrated. Wind and sonic temperature is tran*itted serially via RS-232 and RS-485. Signals from up to 4 additional voltage devices may also be included in the serial string. The sensor installs on standard 1 inch pipe.
