Frequently asked questions
What does '3D' mean on the ZUA3?+
It measures wind along three axes, outputting U, V and W vector components in addition to standard wind speed and direction.
What is the maximum output rate?+
32 Hz, matching the internal sample rate; lower rates of 1, 2, 4, 8, 10, 16 or 20 Hz can be selected.
What material is the ZUA3 housing?+
316L stainless steel.
Does the ZUA3 measure temperature?+
Yes, it derives sonic temperature from the speed of sound, over a range of -40°C to +70°C.
