Use the following procedure to mount the sensor normally to a vertical 1-
inch International Pipe Standards (IPS) pipe. WS425FIX30 is suitable for
the 1-inch IPS vertical pipe and WS425FIX60 is suitable for a 60-mm
vertical pipe (Europe). See Figure 2 on page 24 for details.
To mount the sensor, do the following:
1. Remove the hex-socket bolt or standard screw shown in Figure 2
on page 24 (use 3/16-inch Allen key or a crosshead screwdriver).
2. Connect the cable to the sensor, routing it through the adapter.
3. Attach the adapter to the sensor body and tighten the bolt.
4. Run the cable out of the adapter slot between the sensor and the
clamp. Optionally, you can run the cable inside the vertical pipe.
5. Place the sensor on the pipe and slightly tighten the clamp’s bolt.
6. Align wind direction as explained in section Alignment on page 27.
