Mounting MetPak RG
MetPak RG uses a mounting clamp suitable for attaching to a vertical pipe with a
diameter of 30-58mm (1.2 to 2.3 inches). When mounting MetPak RG, consider the
position, orientation and alignment of the unit.
Note that the mounting pipe should first be degreased and when assembling the
MetPak clamp assembly the outer clamp nuts need to be tightened evenly to a
torque figure of 3 Nm.
The moving plate part of the clamp needs to be reversed for poles below 38 mm
diameter.
Position
It is the responsibility of the customer to ensure that the MetPak RG is mounted in
a position clear of any structure, including the mounting post, which may obstruct
the airflow or induce turbulence.
CAUTION. Do NOT mount the MetPak RG in close proximity to high-powered
radar or radio transmitters. A site survey may be required if there is any
doubt about the strength of external electrical noise.
Orientation
Normally, the MetPak RG is mounted on a vertical pole, ensuring a horizontal
Measuring Plane (see Figure 11).
For indoor use the unit may be mounted with the Measurement Plane set to any
required orientation.
Alignment
The MetPak RG Wind Sensor should be aligned to point to North, or other required
reference direction.
There are two arrows, a coloured rectangle, and an alignment notch on the
WindSonic Wind Sensor that should point to North to aid alignment (See Figure
11).
Note.
It is usually simpler to work first with a compass at ground level and identify a
suitable landmark and its bearing.
Note. The North arrow alignment marker is now rotated by 180 degrees
compared
Interference
Always check the installation to ensure the MetPak RG is not affected by other
equipment operating locally, which may not conform to current standards, e.g.
radio/radar transmitters, boat engines, generators etc.
See Para 2.1 for guideline details.
