Shown below is a Delta OHM HD2003 3-axis ultrasonic anemometer (undergoing testing in our office):

The instrument measures 3 velocity components (u, v, w velocity components) and 3 additional quantities (temperature, humidity, and barometric pressure), and calculates a number of derived quantities (wind speeds and directions, sonic temperature, and wind gust), as shown in the screen capture below:

In this application, the data collected by HD2003 is logged by Delta OHM HD35EDW-MB wireless data logger with MODBUS-RTU input.
