Introduction & Overview – S2 Sonic Anemometer
2.1
Overview
Climatronics’ sonic anemometer, P/N 102779, is designed as a stand-alone
sensor to provide accurate measurements of wind speed and wind direction. An
internal fluxgate compass and an analog output module are available as options.
The unit has no moving parts and is ideally suited for use wherever reliable,
maintenance free operation over a wide operating range under adverse operating
conditions is required.
Please see the configuration table on the last page of this manual.
Compare it to the serial number label on your sensor for your exact
configuration.

Installation
Be sure to mount the sensor in a clear, open area to
minimize any turbulent effects caused by local
obstructions (e.g., trees, buildings, etc.). The sensor is
installed on Climatronics P/N 102778 QuickMount. The
keyway in the connector on the base of the sensor is
matched to the keyway on the mount.
Attach the sensor to the 102778 QuickMount by
inserting the sensor into the top of the mount, attaching
the latch springs to the clips on the bottom of the
sensor and snapping them down to lock the sensor in
place. You may need to rotate the sensor 180° to allow
the keyway to seat properly.
If your sensor is not equipped with a fluxgate compass you will need to align the
posts with the black marks towards either True North or Magnetic North
depending on your application.
On the 102778 QuickMount, loosen the thumb screws in the bottom of the mount
that attach it to your vertical ¾ inch pipe, rotate the sensor to North, then
retighten the set screws.
The connector keyways assure correct alignment if the sensor is removed and
re-installed at any time.
Please refer to Figures 1 and 2 for reference.

The sensors’ pin designations are as follows:
Warning: Do not short any of these wires to ground or to each other.

User Defined Options
Fluxgate Compass
An optional internal fluxgate compass is available with the Sonic Weather
Station. Check the sensor’s configuration to see if it is installed.
Note: The wind direction output will be relative to magnetic north if the fluxgate
compass is selected. To change Magnetic North to True North, see MD
command in Appendix A.
Analog Outputs
An optional analog output module is available for the Sonic Weather Station.
The module is factory configured to present Wind Speed and Wind Direction in
any one of four ranges (0-1, 0-2.5, 0-5, or 1-5 Volts). Check the sensor’s
configuration to see if it is installed.
Note: Analog output range cannot be reconfigured without returning unit to
factory.

User Interface
The output of the Sonic is a fixed length, ASCII serial data stream. The serial
output is factory set for 9600 baud, no parity, 8 data bits, with 1 stop bit (N, 8, 1).
The output interval is factory set to once per second. Other baud rates and
output intervals are available, see Appendix A for instructions on how to change
these settings. The data is easily viewed and can be displayed and captured
using Climatronics WeatherView Software or Windows HyperTerminal which is
supplied with all Windows operating systems except Vista.
To find
HyperTerminal click Start, Programs, Accessories, Communications,
HyperTerminal.
An example of the output format is shown below:
01+H0012 02+006.8 03+063.2CR/LF
The first parameter is the serial number of the sensor (H0012), the second
parameter is the wind speed, and the third parameter is the wind direction. All
parameters have fixed decimal points with leading zeroes and the string ends
with a carriage return and line feed.
Note: The optional wind tracker output is a special hexadecimal data string
that cannot be viewed as shown in the above example.
The default wind speed output is in m/sec, this can be changed with the SU
terminal command. Please refer to Appendix A for more information.
Polled data mode (RS232 or RS485)
The sensor can be set for polled data mode instead of continuous serial output
by setting the serial trigger string while in terminal mode. Refer to the ST
terminal command in Appendix A. Additional help for setting this option is
available in the sensor’s ST menu. Type ST↵ for help with this command.
SDI-12 Interface
In addition to the above communications methods, the sensor can be polled by
an SDI-12 Master Station for data. This operates completely independent of the
RS232 or RS485 communications and can be used in conjunction with those
methods. Data are polled using a series of SDI-12 commands. Please see
appendix A for a list of supported SDI commands. The default SDI Address for
the Sonic is zero. The output format has the same basic structure as the RS232
output format, Wind Speed and Wind Direction.

Calibration
The sensor requires a wind tunnel for calibration. Climatronics can provide NIST
traceable calibration in our wind tunnel.
We also offer a “Cone of Silence” Block of Acoustic Foam for field health checks
as well as a portable wind tunnel in a transit case for more rigorous field audit or
health checks.

Maintenance
Because the sensor has no moving parts to wear out, periodic maintenance is
not required. In extremely corrosive environments, the condition of the connector
used to mount the sensor should be checked. There are no adjustments or user
repairable parts located inside the sensor.

Appendix B
Theory of Operation
Winds
Climatronics’ sonic anemometer operates on the principal that the speed of the
wind affects the time it takes for sound to travel from one point to a second point.
If the sound is traveling in the direction of the wind then the transit time is
decreased. If the sound is traveling in a direction opposite the wind then the
transit time is increased. This principal is well known and is the basis of most
sonic anemometers.
Fluxgate Compass
The P/N 11709 internal compass is low power and compact, and is a complete
compass or magnetic sensor module that integrates easily into the Sonic. The
internal compass uses two magneto-inductive sensors, which change inductance
with different applied magnetic field strengths, to sense magnetic fields.
The Sonic microprocessor measures the output of the internal compass and
corrects the wind direction data for the orientation of the sensor. The output of
the Sonic wind direction is relative to magnetic North when a compass has been
specified.
