Message From Rob
Campbell Scientific Australia (CSA) is backed by Campbell Scientific (CS) Incorporated in the United
States. As well as supporting CS products we are also distributors of other world class instrumentation
from international manufacturers. Our vision is to supplement our core business with CSA designed and
manufactured products. The 2011 release of Hydrosense II has been a tremendous success and we have
products currently under development for release next year.
We will shortly reach another milestone when our first shipping container of product from the USA arrives to stock the warehouse
shelves at our new larger premises. Until recently our business was unable to sustain such large volume shipments and all goods were air
freighted to Australia. This initiative will help maintain prices at competitive levels as well as enable CSA to hold more stock in country.
Last month I was fortunate to meet many of our distributors and customers while recently touring South East Asia. Many Australian
companies are active in the region and our products are an important component in a range of turnkey solutions in environmental and
compliance monitoring applications. To strengthen our support in the region we have added a distributor, P.T.CERNA Corporation, in the
Philippines, details to be available soon on our website. We expect to announce further initiatives in South East Asia and Australia later
this year.
As a global organization CS has recently embarked on a strategic analysis of worldwide company operations. As the group has grown,
CSA included, product development capability and expertise in specific industries has developed in the regional companies. Often the
experiences and needs of our customers spawn ideas for new products or product enhancements, so we encourage your feedback as end
users of CS solutions. The annual September group companies’ conference will review the findings to date and make recommendations
to ensure CS and their customers can benefit from this expanding global presence and knowledge to remain an important provider of
measurement instrumentation and services to governments, corporations and small business clients.
Finally Steve Bailey, Gavin Hewitt and myself will be attending the AHA Conference in Melbourne from the 21st August. As Gold sponsors,
CSA have been exhibiting for many years now and it’s been proven to be a great way to touch base with other key groups working in
hydrology applications throughout Australasia. If you’re attending please drop by and say hello. You’ll find us at Stand 2.

New Operating System for CR800, CR1000, CR3000
Campbell Scientific is dedicated to continually improving our products in order to better meet our customers’ needs and to keep pace
with changes in technology. These improvements are particularly evident when looking at enhancements added to our data logger
operating systems over the years. These are some of the great new features available with the upgrade from OS 24 to OS 25:
Enhanced diagnostics for Campbell wireless sensor networks (CWSNs)
Support for memory expansion with compact flash cards larger than 2 GB
Support for the new NL240 Wi-Fi interface
For a detailed list of features added from OS 24 to OS 25, please visit www.campbellsci.com/70_103.
New features have increased the size of OS 25 so that CR800 and CR1000 data loggers manufactured before September 2007 (those
with 2 MB of SRAM) will have to be directly connected to a PC running Device Configuration Utility to load the larger OS.* If you have a
2 MB datalogger and remote OS download is necessary (i.e., need to use TCP/IP), you can have your 2 MB datalogger updated to 4 MB.
For details and pricing on the OS 25 memory upgrade, contact our office on +61 (0)7 4401 7700.
* All CR3000 data loggers have 4 MB of SRAM and will
accept direct or remote downloads of OS 25. CR800s with
serial numbers greater than 3605 and CR1000s with serial
numbers greater than 11832 have 4 MB SRAM and will
accept direct or remote downloads of OS 25.

Station Provides Flood Warning & Road Weather Data
Case Study
Networks using the ALERT protocol are designed to give
immediate access to data that indicates the likelihood of flood
conditions. ALERT stations typically are set up to acquire and
transmit hydrological and meteorological data on a timed and
event basis. What many users don’t realize is that Campbell
Scientific data loggers that are used to run ALERT stations have
plenty of capability to spare, and that capability can be leveraged
to perform a variety of services.
Douglas County, Colorado, in conjunction with Denver’s Urban
Drainage Flood Control District (UDFCD), operates an extensive
ALERT network to monitor potential flood conditions. In 2008,
the county decided that the next ALERT site they set up should
also have a camera to monitor stream and road conditions, and a
road-temperature sensor to aid the Public Works department with
winter maintenance. This would give the station the abilities of a
road-weather information system (RWIS).
In addition to this normal flood-warning role, the CR1000 acts
as a web server, using cellular communications to provide other
users with near-real-time images of the stream, along with the
same type of data sent to the ALERT network, and temperatures
for water, air, and road surface. A staff gauge was painted on one
of the bridge piers to be visible by the camera, and this can be
used to verify the performance of the water-level sensors. As a
public service, the CR1000 is also configured to use its Internet
communication abilities to send current data and camera images
to the Weather Underground website (wunderground.com).
To accomplish this task, Water & Earth Technologies of Fort Collins,
Colorado, worked with Campbell Scientific to design and build the
new site as a multipurpose system. The new system has a variety
of features:
This weather station has no access to ac power, but is able to
rely solely on solar power. The programmability of the CR1000
enabled use of power-saving techniques such as turning off the
camera at night and powering down hungry sensors when they
are not needed.

Campbell Scientific data loggers are great foundations for ALERT
systems. And they are flexible enough to meet expanding needs
and interesting challenges.

Oz Flux 2012
Methven, New Zealand
In the first week of July, Dr David Hammond and David Boadle from CSA travelled to Methven, New Zealand, to attend the Ozflux annual
conference. The hosts for the conference were Landcare Research New Zealand, the National Institute of Water and Atmospheric Research
(NIWA) and CSIRO. It was apparent from the number of attendees at the conference that
the Flux research community in Australia and New Zealand is thriving, and it was good
to see so many new researchers utilising the capabilities of flux monitoring equipment
within their research fields.
After an opening presentation providing updates on the Terrestrial Ecosystem Research
Network (TERN) by Helen Cleugh of CSIRO, the conference speakers gave presentations
on a wide variety of topics over the course of the 3-day conference. All around Australia
and New Zealand Campbell Scientific equipment is being used in flux monitoring
applications, whether it’s to determine how much CO2 is left behind after mountain
ash forest fires, how much groundwater disappears through Evapotranspiration, or to
quantify the sources of Methane and Nitrous Oxide in agricultural locations, to name
just a few applications, Campbell Scientific flux monitoring systems play a pivotal role by
providing accurate, reliable data utilising industry leading sensors and data acquisition
devices.
The newest flux measurement offering from Campbell
Scientific is the IRGASON integrated open-path analyser and
sonic anemometer, specifically designed for eddy-covariance
flux measurements. The IRGASON simultaneously measures
absolute CO2 and water vapour densities, air temperature,
barometric pressure, three-dimensional wind speed, and sonic
air temperature. For further information on the IRGASON or
any other Campbell Scientific flux monitoring systems, contact

Lightning Warning System For OH&S.
State-Of-The-Art Weather Monitoring System
Case Study
McConnell Dowell, an Australian and International engineering,
construction, building and maintenance company, is using Campbell
Scientific data loggers and sensors within its new state-of-the-art
weather monitoring and marine navigation system installed at Hay
Point in North Queensland. The main purpose of the system is for
Operations Health & Safety, ensuring safe working conditions for
McConnell Dowell personnel. Campbell Scientific equipment being
used in the system includes three CR800 data loggers, three RIMCO
rain gauges, one CS475 radar sensor being used for wave height
monitoring, and the Campbell Scientific CS110 and Strike Guard
Lightning Warning system.
Above: Touchscreen - Real-time weather data with live video images.
The lightning warning system provides early
warning of the potential for lightning strikes
by measuring the local vertical component
of the atmospheric electric field at the earth’s
surface. Combined with the Strike Guard
optical-coincidence lightning sensor, which
detects actual lightning strikes for up to
32 km from the installation site, a decision
making algorithm provides early warning to
site operators of the potential for lightning within the vicinity of the
construction site. Integrated with the other measured parameters,
the data is used to assist in decision making for Occupational Health
& Safety.
McConnell Dowell now has the most unique weather monitoring
system in Australia for its purpose. James Palmer from McConnell
Dowell said ‘the system has been of great benefit and vital importance
from a safety and commercial perspective, and the equipment is very
specialised for the project we have undertaken.”
Work on interfacing the Campbell Scientific equipment into a
complete turnkey solution for McConnell Dowell was undertaken
by Marcom Watson, a Launceston based company specialising in
Marine Electronics and Radio Communications and a recommended
Campbell Scientific equipment integrator. Brett Victory, managing
director of Marcom Watson, and their senior engineer Colin Kew,
headed up the system installation in partnership with McConnell
Dowell’s Radio Communications Marine Navigations and Weather
Systems supervisor James Palmer. James said “Brett Victory and the
Marcom Watson team have been fantastic. I could not have asked
for a more experienced professional and trustworthy team to work
with.” Dr David Hammond, Application Engineer at Campbell Scientific
Australia, said “it was a pleasure working with Brett and the team at
Marcom Watson in delivering state-of-art measurement systems they
could interface into their custom-built weather monitoring system for
McConnell Dowell. The quality of the final turn-key weather monitoring
system provided by Marcom Watson is first class”.
Marcom Watson is an Australian company originally formed in 1965 to
provide product and support services to commercial and professional
users of radio communications and maritime electronics.

New Lightning Warning System
New Product
A variety of applications can benefit from the LW110 Lightning
Warning System. Outdoor spectator events such as ball games,
golf tours, and soccer matches can use this system to protect
players and fans. Public swimming pools and other outdoor
venues can also benefit.
Additionally, the system is ideal for industrial facilities. Personnel
working in exposed locations or facilities dealing with explosives
or fuels can take protective measures when warned of lightning
danger. The LW110 can then trigger its alarm to indicate when
the danger has passed, allowing work to recommence as soon as
possible.

How To Access Stored Data Records Using CRBasic Code
Tips and Tricks
Nearly every program written for a Campbell Scientific data
logger will include one or more data tables as a method of storing
measurements or variable states for later analysis or diagnostics.
In some cases it can be useful to recall previous stored records
during run time for a multitude of operations. Once data table
records are written it is possible to perform operations on previous
data stored to maintain data integrity, trigger events or prevent
double handling of data using an array for operations such as
running averages or totals.
Usage
Accessing data table records requires the use of special syntax
available in CRBasic, this syntax is uses the form
TableName.FieldName (FieldNameIndex,RecordsBack)
This syntax will access data from a specific Field of a DataTable
Record. The TableName is the name of the table where the value
to be accessed is stored. The table can be a user-defined data
table or the status table. FieldName is the name of the field in the
table, and it is always an array even when it consists of only one
variable. FieldNameIndex specifies the array variable from which
to retrieve data. RecordsBack specifies the number of records back
in the DataTable the desired value resides (1 is the most recent
record stored).
In the below example the current measured temperature (AirTemp)
is stored in a data table named Temperature. These stored records
are retrieved to calculate the change in temperature recorded
15 records ago (1 minute storage) compared to the current
temperature.
Public AirTemp, Tdiff
DataTable(Temperature,True,-1)
DataInterval(0,1,min,5)
Sample(1,AirTemp,IEEE4)
EndTable
BeginProg
Scan(1,min,5,0)
Therm107(AirTemp,1,1,1,0,_50Hz,1,0) ‘ Measure Air temperature
using a 107 thermistor
‘ Calculate 15 min temperature difference
Tdiff = Temperature.AirTemp(1,1) – Temperature.AirTemp(1,15)
CallTable Temperature
NextScan
EndProg
This ability to access previous records within a data table allows
the calculation of running totals, differences or averages to be
achieved without maintaining an array. This syntax can also be
used with other data table access options to keep track of fill
times, new records or event based recording. A list of available
syntax commands are below:
TableName.EventCount Used to access the number of data
storage events that have occurred in an event driven DataTable.
TableName.EventEnd
Used to determine when the last
record of an event is sent to the DataTable.
TableName.FieldName
Used to access data from a specific
Field of a DataTable Record.
TableName.Output
Used to ascertain whether data was
written to the Output DataTable the last time that the DataTable
was called.
Returns the record number of the
TableName.Record
record output n records back.
Returns either 1 or 0 to indicate
TableName.Tablefull
whether a fill and stop table is full or whether a ring-mode table
has begun overwriting its oldest data.
TableName.TableSize
Returns the size allocation, in
number of records, of the selected DataTable.
TableName.TimeStamp Returns one time stamp element of
the record output n records back.
In the next example the syntax TableName.Output will be used to
detect new records and calculate a running total of rainfall in the
previous 1, 12, 24, 48 and 72 hour periods. The rainfall is stored
at one hour intervals in the Hourly data table and each record is
accessed and added to an accumulator, when the accumulator
reaches each multiple of hours the current value is moved to a
corresponding variable.
If Hourly.output(1,1) = True Then ‘ If new Hourly table record
RainTotal = 0
‘ Reset the raintotal variable
For RainDataPos = 1 To 72 ‘ 72 hours at one hour per record
RainTotal = RainTotal + Hourly.Rain_mm(1,RainDataPos) ‘ Get
Rain record from RainDataPos
If RainDataPos = 1 Then RainTotal1Hr = RainTotal
If RainDataPos = 12 Then RainTotal12Hr = RainTotal
If RainDataPos = 24 Then RainTotal24Hr = RainTotal
If RainDataPos = 48 Then RainTotal48Hr = RainTotal
If RainDataPos = 72 Then RainTotal72Hr = RainTotal
Next RainDataPos
EndIf
The use of data access syntax within your program can greatly
simplify coding during testing data tables and allows operations
on your data to be performed without maintaining complicated
arrays, time intervals or incrementing variables.
