Overview
The RM Young 81000 Ultrasonic 3D Anemometer is a 3D wind sensor with no moving parts. While other 2-D anemometers ignore the vertical wind component, the 81000 provides a complete picture of the wind. Constructed with three opposing pairs of ultrasonic transducers, it provides accurate and reliable wind measurements.

Durable
The sensor features robust construction with 3 opposing pairs of ultrasonic transducers supported by stainless steel members. This arrangement provides rigidity to the anemometer while offering a measure of protection to the transducers. The transducers are arranged so that measurements are made through a common volume, thereby improving the validity of the measurement. A fast, 160 Hz sampling rate ensures superior measurement resolution.

Customizable
The RM Young 81000 Ultrasonic 3D Anemometer features (4) voltage output channels. Serial RS-232 and RS-485 outputs are available as well. For applications requiring synchronized analog measurements, Model 81000V includes four voltage input channels instead of voltage outputs. Wind, sonic temperature, and voltage input data are transmitted serially. A variety of preset or custom output format options may be selected by the user. The 81000 installs on standard 1" (IPS) pipe. Wiring connections are housed in a convenient weatherproof junction box.

Questions & Answers
How much more accurate is the 3D than the regular Ultrasonic Anemometer?
At a wind speed of 0 to 30 m/s, the basic RM Young Ultrasonic Anemometer has an accuracy of +/- 2% or 0.1 m/s while the RM Young Ultrasonic 3D Anemometer has an accuracy of +/- 1% +/- 0.05 m/s.
There are large gaps in my data and some missing points, what could be causing this?
Often these issues are due to physical impediments such as birds and their droppings. The anemometer must be clean and free of debris to ensure the most accurate readings.
How often does the anemometer need calibrated?
RM Young recommends a calibration frequency of 1 year from previous or factory calibration.
What’s the difference between the YOUNG Ultrasonic 3D Anemometers 81000 and 81000V sensors?
The 81000 outputs voltage and serial, whereas the 81000V has voltage input with serial output. With the 81000V, there is no option for voltage output.
