The Ultrasonic Wind speed and Wind direction sensor
10 Installation Guidelines
The HY-WDS2E has been designed to meet and exceed the stringent standards listed in its
specification. Operating in diverse environments all over the world, HY-WDS2E requires no
calibration and adjustment whatsoever.
As with any sophisticated electronics, good engineering practice should be followed to ensure
correct operation.
Always check the installation to ensure the HY-WDS2E is not affected by other equipment
operating locally, which may not conform to current standards, e.g. radio/radar transmitters,
boat engines, generators etc.
·Avoid mounting in the plane of any radar scanner – a vertical separation of at least 2m
should be achieved.
·Radio transmitting antennas, the following minimum separations (all round) are suggested
VHF IMM – 1m
MF/HF – 5m
Satcom – 5m (avoid likely lines of sight)
·Use cables recommended by Hongyuv. If cables are cut and re-connected incorrectly
(perhaps in a junction box) then EMC performance may be compromised if cable screen
integrity is not maintained.
·Earth loops should not be created – wire the system in accordance with the installation
guidelines.
· Ensure the power supply operates to the HY-WDS2E specification at all times.
· Avoid turbulence caused by surrounding structures that will affect the accuracy of the
HY-WDS2E such as trees, masts and buildings. Ideally sensors should be mounted on the
prevailing wind side of the site.
The WMO make the following recommendations:
The standard exposure of wind instruments over level open terrain is 10m above the ground.
Open terrain is defined as an area where the distance between the sensor and any
obstruction is at least 10 times the height of the obstruction.
If mounting on a building then theoretically the sensor should be mounted at a height of 1.5
times the height of the building.
If the sensor is to be mounted on a mast boom, part way up a tower or mast, then the boom
should be at least twice as long as the minimum diameter or diagonal of the tower. The boom
should be positioned on the prevailing wind side of the tower.
