1 FOREWORD

Thank you for purchasing the WindSonic manufactured by Gill Instruments Limited. The
unit has no customer serviceable parts and requires no calibration or maintenance. To
achieve optimum performance we recommend that you read the whole of this manual before
proceeding with use. Do NOT remove black “rubber” transducer caps.

Gill products are in continuous development and therefore specifications may be subject to
change and design improvements without prior notice.

The information contained in this manual remains the property of Gill Instruments and
should not be copied or reproduced for commercial gain.

2 INTRODUCTION

The Gill WindSonic wind sensor is a very robust, lightweight unit with no moving parts,
outputting wind speed and direction. The units of wind speed, output rate and formats are all
user selectable.

The WindSonic can be used in conjunction with a PC, data logger or other device, provided
it is compatible with one of the standard communication formats provided by the
WindSonic.

WindSonic (option 2 or 3 only) is designed to connect directly to the Gill WindDisplay unit
to provide a complete wind speed direction system.

WindSonic (options 1, 2 and 3) may be configured using Wind software which is available,
free of charge, from the Gill website www.gillinstruments.com. The output message format
can be configured in Gill format, in Polar or UV (2-axis) format, and to either Polled
(requested by host system) or Continuous output. Alternatively, it can be configured in
NMEA (0183 Version 3). These are described in Section 9 MESSAGE FORMATS.

WindSonic (option 4) SDI-12 may not be re-configured in any Gill output format and format
is SDI-12 (V1.3) and described in Section 14 SDI-12 COMMANDS.

3 FAST TRACK SET-UP

If you are in a hurry to try out the WindSonic (options 1, 2 or 3) and are familiar with Gill
equipment and coupling to a PC using RS232, go to the following sections:

 Section 7 INSTALLATION
 Section 9 MESSAGE FORMATS
 Section 10 CONFIGURING

After you have successfully set up the WindSonic, we strongly advise that you then go back
and read the rest of the manual to ensure that you get the best results from the WindSonic.

4 PRINCIPLE OF OPERATION

The WindSonic measures the times taken for an ultrasonic pulse of sound to travel from the
North transducer to the South transducer, and compares it with the time for a pulse to travel
from S to N transducer. Likewise times are compared between West and East, and E and W
transducer.

If, for example, a North wind is blowing, then the time taken for the pulse to travel from N
to S will be faster than from S to N, whereas the W to E, and E to W times will be the same.
The wind speed and direction can then be calculated from the differences in the times of
flight on each axis. This calculation is independent of factors such as temperature.

7 INSTALLATION

Do NOT remove the black “rubber” transducer caps. Warranty is void if the coloured
security seal is damaged or removed.

7.1 Installation Guidelines

The WindSonic has been designed to meet and exceed the stringent standards listed in its
specification. Operating in diverse environments all over the world, WindSonic 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 WindSonic is not affected by other

equipment operating locally, which may not conform to current standards, e.g.
radio/radar transmitters, boat engines, generators etc.

Guidelines –

o Avoid mounting in the plane of any radar scanner – a vertical separation

of at least 2m should be achieved.

o 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 Gill. 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 WindSonic specification at all times.

Avoid turbulence caused by surrounding structures that will affect the accuracy of the
WindSonic 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.

WindSonic Doc No 1405 PS 0019 Issue 25 February 2017

17

7.2 Bench system test

Note: Prior to physically mounting the WindSonic in its final location, we
strongly recommend that a bench system test is carried out to confirm the
system is configured correctly, is fully functional and electrically
compatible with the selected host system and cabling (preferably utilising
the final cable length). The required data format, units, output rate, and
other options should also all be set up at this stage.

7.3 Electrical

7.3.1 Cable

Cable type

A RS422 compatible cable should be used, with the number of twisted pairs matching the
application.

Generic description – Twisted pairs with drain wire, screened with aluminised tape,
with an overall PVC sheath of 6mm-12mm outer diameter. Wire size 7/0.2mm (24 AWG).

The table shows some suitable manufacturers’ references; other manufacturers’ equivalents
can be used.

Cable length

The maximum cable length is dependent on the chosen communication format (RS232,
RS422 or RS485 (point to point), the baud rate, and, to a lesser extent, on the cable type and
the local electrical ‘noise’ level.

The table shows the typical maximum lengths at the given baud rates, using the
recommended cable. If any problems of data corruption etc. are experienced, then a slower
baud rate should be used. Alternatively, a thicker or higher specification cable can be tried.

complete wind speed and direction system.

To interface to a non NMEA WindDisplay the WindSonic is set by default for Polar

(M2) and 9600 (B3) configuration settings.

When coupled to a WindDisplay, the WindSonic can be used as supplied, however if a
fault occurs the WindDisplay may lock into the last valid reading. Re-configuring the
WindSonic to Fixed Field output (O2) will ensure that any fault is flagged on the
WindDisplay.

After coupling to a WindDisplay, the Wind Speed units and the Averaging period can
be selected using the WindDisplay controls. See the WindDisplay User Manual.

Note that although the WindDisplay can display wind speed in various units, these are
calculated within the WindDisplay. The data coming to the WindDisplay must be in
metres/sec (the factory default output setting).

Notes

1. WindSonic Option 2 or 3 must be used set for RS422 output (E2 Mode).

2. Use the WindSonic in the factory default mode for the Meteorological Wind

Display – i.e. do not reconfigure.

3. If used with a Marine NMEA 9600 Baud or4800 Baud WindDisplay set the

Wind Sonic for NMEA (e.g. M5) and 9600 Baud (B3) or4800 Baud (B2).

4. The WindDisplay can provide power to the WindSonic.
