3-AXIS ULTRASONIC ANEMOMETER
WindMaster RA
The right-angled head, for flow along the mounting axis.
WindMaster RA carries a right-angled head rather than the symmetrical head of the standard WindMaster. That changes where the instrument can sit relative to the flow being measured, which matters when the mounting arrangement would otherwise put the structure in the measurement path.

Right-angled head
Fits tight installations
20 Hz output rate
32 Hz option available
RS232 and analogue outputs
12-bit data, 14-bit option
-40 °C to +70 °C
IP65 rated
WHERE IT SITS
WindMaster RA in the WindMaster range
Within the WindMaster family the models differ by measurement range, output rate, build and approvals rather than by measurement principle.

BEFORE YOU SPECIFY
Is the WindMaster RA the correct configuration?
Before specifying, confirm:
- the wind speed range the site actually sees
- the output rate the receiving system needs
- the operating temperature and whether heating is required
- any approval or certification the installation demands
- the mounting arrangement and cable or connector choice
- the interface and output the receiving system expects
If those match, the WindMaster RA provides that configuration.
