Before installing, see note at Section 7.2 Bench system test.
8.1 Orientation
Normally the WindSonic is mounted on a vertical tube, ensuring a horizontal Measuring
Plane.
See Figure 3 Alignment & Mounting details
For indoor use the unit may be mounted with the Measurement Plane set to any required
orientation.
8.1.1 Alignment
The WindSonic should be aligned to point to North, or any other reference direction –for
example, the bow of a boat.
There are two arrows, a coloured rectangle, and an alignment notch to aid alignment.
See Figure 3 Alignment & Mounting Details
Note:
It is usually simpler to work first with a compass at ground level and identify a
suitable landmark and its bearing.
8.1.2 Mounting
The support tube
requires three 3 equally spaced holes, tapped M5, 7.5mm from the top of
the tube. Pass the cable (fitted with the 9 way Clipper plug) through the tube. See Fig 3.
Note:
the customer must fit appropriate strain relief to the cable.
Connect the plug by twisting it whilst pushing it gently into the socket on the WindSonic.
When it locates, twist the outer sleeve clockwise to connect and lock the plug.
Fix the WindSonic to the tube using the 3 stainless steel screws provided. (Maximum
mounting screw torque 1.5 Nm for aluminium and 3 Nm for stainless steel.)
It is the responsibility of the customer to ensure that the WindSonic is mounted in a position
clear of any structure, which may obstruct the airflow or induce turbulence.
Do NOT mount the WindSonic in close proximity of high-powered radar or radio
transmitters. A site survey may be required if there is any doubt about the strength of
external electrical noise.
The Mounting Bracket
(1771-PK-115)
Mount the Sensor on to the bracket mount and if using a Wind Sensor align so that the
Sensor North Marker points to the bracket pole.
Secure the sensor to its mount using screws and washers supplied in the Sensor Box.
Torque screws to a maximum of 4 Nm.
The Bracket uses a clamp suitable for attaching to a vertical pipe with a diameter of 30-
58mm. When mounting the Bracket Sensor, consider the position, orientation and alignment
of the unit. Mount at the top of a Pipe to ensure a clear unobstructed measurement view.
Note that the mounting pipe should first be degreased and when assembling the Bracket
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.
Screw an Earth cable minimum of 6mm
2
to the Bracket chassis using Screw and Terminal
Tag fixings supplied.
