RAIN BIRD
Weather Station -- Model - PRO
1.0 GENERAL:
The Rain Bird “Model PRO” Weather
Station, when used in conjunction with
the Rain Bird MAXI 5, MAXI “Nimbus”
or MAXI “Cirrus” Central Control
system, provides the irrigation manager
with a powerful tool to aid in the
growing of lush, healthy, green
turfgrass, while conserving important
resources, such as water, power, etc.
The MAXI 5, MAXI Nimbus or MAXI
Cirrus software interrogates the Weather
Station to gather information that has
been gathered on a daily basis, on 5
second intervals for short haul modem
only, of the climatic conditions that
affect the irrigation application for the
area.
The MAXI 5, MAXI Nimbus or MAXI
Cirrus software subjects the climatic
information that it gathers to a version of
the modified Penman Equation. The
Penman Equation has been proven
through over 35 years of university
research, to be one of the most reliable
predictors of turfgrass water use
requirements.
The Weather Station monitors the
following climatic conditions:
Rainfall
Wind Speed & Direction
Air Temperature
Relative Humidity
Solar Radiation
The basic PRO Weather Station
configuration includes sensors to
monitor these conditions, a micrologger
to capture this data, a modem to
communicate the information to the
MAXI Central Computer and a power
supply.
The Rain Bird Model “PRO” Weather
Station is available in two (2) basic
configurations;
Model PRO-SH, which is a
direct wire system intended for
use when the weather station is
within 20,000 feet of the MAXI
Central Computer and
communication is via a wire
path, between the weather
station and the computer.

Weather Station - Model “PRO”
Nov., 2001 Page 2Model “PRO”- Weather Station
Cozz GT27145B
Model PRO-PH, which is a
phone modem system for use
when the weather station is
further than 20,000 feet from the
MAXI Central Computer or
when they cannot be connected
by a communication wire path.
The system communicates
utilizing a standard, dedicated
phone service.

3.0 WEATHER STATION SITE SELECTION:
Site selection for the Weather Station is
one of the most crucial steps in a
successful installation and an efficiently
operating irrigation system. The site
selection will greatly impact the
accuracy of the meteorological data
collected by the station. The site
selection process has many constraints
placed on it, and although the “perfect”
site is often non-existent, the following
generalities should be kept in mind.
In general, the site should be
representative of the general area of
interest and reflect the general conditions
of the project’s turf. The more “typical”
the site, in this regard, the more useful
will be the information gathered. The
site should also be away from the
influence of obstructions such as
buildings, trees, etc.
The weather station should not be
located where sprinkler irrigation water
will strike sensors or instrument
enclosure. The turf around the weather
station needs to be irrigated however - so
it is recommended that half-circle
sprinklers be placed around the base of
the weather station and ”throwing OUT’
away from the weather station. In this
way the turf can be irrigated and at the
same time water can be kept off the
sensors and instrument enclosure of the
weather station.
The sensors of the weather station
should be eight (8) to ten (10) feet above
the turfgrass. Remember that the roof
of a building IS NOT a good site for the
weather station.
The weather station does NOT need to
be “hidden”. The Rain Bird weather
station has been engineered to be
aesthetically pleasing. The urge to
“hide” the station needs to be balanced
with the selection of the most “typical”
turfgrass area. The station should NOT
negatively impact the turfgrass
environment or utility. In fact, many
installations prominently display the
Weather Station to demonstrate their
commitment to water conservation.
If the site may be prone to vandalism, an
open, chain-link, 6 foot high security
fence with a lockable access gate should
be placed around the weather station.
The fence shall be a minimum of eight
(8) feet out from the weather station on
all sides and should be a type that will
not interfere with the accuracy of the
sensors.
In your selection of a site - try to avoid
sites on or near open dirt fields and
asphalt parking areas. These sites are
prone to high invective heats that can
distort the information. Any areas that
are within 90 to 100 feet “up wind” of
the weather station can adversely affect
the weather station reading accuracies.
The requirements of each weather station
sensor must be considered when
selecting the proper location for a
weather station site. In addition to these
generalities, each sensor has its own
specialized constraints. While complete
information is available, upon special
request, for each individual sensor, the
following are the highlights of each.

Weather Station - Model “PRO”
Nov., 2001 Page 4Model “PRO”- Weather Station
Cozz GT27145B
(a) TEMPERATURE AND
RELATIVE HUMIDITY:
Sensors should be located over an open
level turf area at least 30 feet in
diameter. The surface should be the
typical turfgrass of the area in interest.
Sensors should be located a distance
away of at least four (4) times the height
of any nearby obstruction and at least 90
feet from large paved areas. Sensors
should be protected from thermal
radiation, and adequately ventilated.
Situations to avoid include:
•large industrial heat sources
•rooftops
•steep slopes
•sheltered hollows
•high vegetation
•shaded areas
•top of a hill
•bottom of a swale
•swamps
•areas where snow drifts occur
•low places holding standing
water
(b) SOLAR RADIATION:
Pyranometers should be located to avoid
shadows on the sensor at any time.
Mounting it on the southern most portion
(northern hemisphere) of the weather
station will minimize the chance of
shading from other weather station
structures. Reflective surfaces and
sources of artificial radiation should be
avoided. The height at which the sensor
is mounted is not critical.
(c ) PRECIPITATION

Weather Station - Model “PRO”
Model “PRO” - Weather Station Page 5 Nov., 2001
GT27145B Cozz
A rain gage should be located over level
ground that is covered with short grass
or gravel. In open areas, the distance to
obstructions should be two to four times
the height of the obstruction.
The height of the opening should be as
low as possible, but should be high
enough to avoid splashing from the
ground.
The gage must be mounted above the
average level of snow accumulation in
areas that experience significant
snowfall.
Standard measurement heights:
1.0 meter +/- 1.0 cm (AASC)
30.0 centimeter minimum
(WMO, EPA)
(d) DETERMINING TRUE
NORTH FOR WIND
VANE OREINTATION
Magnetic declination, or other methods
to find True North, should be
determined prior to installing the
weather station. True North is usually
found by reading a magnetic compass
and applying the correction for magnetic
declination. (Other methods employ
observations using the North Star or the
sun, and are discussed in the Quality
Assurance Handbook for Air Pollution
Measurement Systems, Volume IV -
Meteorological Measurements.) The
magnetic declination is the number of
degrees between True North and
Magnetic North. Magnetic declination
for a specific site can be obtained from a
USFA map, local airport, or through a
computer service offered by the USFS
called GEOMAG (see page 7). A
general map showing magnetic
declination for the contiguous United
States is shown below in FIGURE 2.
Declination angles east of True North are
considered negative and are subtracted
from 0 degrees to get True North.
Declination angles west of True North
are considered positive and are added to
0 degrees to get True North. For
example, the declination for Logan,
Utah is 16 degrees East. True North is
360 degrees minus 16 degrees, or 344
degrees as read on a compass.

INSTALLATION:
For the following procedures - Refer to FIGURE 4 below.
1.0 The Tower for the “PRO”
Weather Station - attaches to a user
supplied poured concrete foundation
- constructed as shown in FIGURE
4 below.
2.0 Dig the required foundation
hole - with a 24” square top
and slanting outward sides,
to the bottom of 32” square.
The “Sloping” sides of the
foundation are very
IMPORTANT in providing
the necessary support to the
weather station tower, in
preventing it from “leaning”
or falling over, due to wind
load on the station.
3.0 Determine the proper location
of the long sweep elbow and
dig a small cavity
to accept the end of the elbow
that will protrude beyond the
concrete base.
4.0 Construct the concrete form
with 2” x 4” lumber and 16p
double-headed nails.
Center the form over the dug
hole. Adjacent to the long
legs of the form that extend
beyond the hole, drive four
stakes into the soil. Level
the form. Secure the form
to the stakes with 8p nails -
making sure that the form
remains “level”.
5.0 Place a piece of duct tape
over one end of the 1 ½”
diameter long sweep elbow.
Insert the elbow into the
hole, with the taped end
into the small cavity that you

Weather Station - Model “PRO”
Nov., 2001 Page 10 Model “PRO”- Weather Station
Cozz GT27145B
have dug on one side of the
hole.
6.0 Insert the other end of the
long sweep elbow into the
center hole in the stainless
steel template. Tape the
end of the elbow with duct
tape.
7.0 Take the three ½” x 12” long
“L” anchor bolts and install
two (2) hex huts on to each
bolt. Insert one in each of
the holes in the template and
install one of the flat washers
and a nut to secure the anchor
bolt to the template.
Refer to FIGURE 5.
8.0 Take the form wire and cut it
into two (2) equal lengths.
Attach one end of one of the
wires to one of the 16p nails
on the form. String the wire
up over the form and to the
long sweep elbow - making a
turn around it. Continue the
wire over to the 16p nail at
the other corner of the form
(located on the same side of
the form as the other nail)
and centering the template
and elbow attach the wire
securely to the nail. Repeat
this same process with the
other piece of form wire -
going to the opposite nails
and further securing the
template, elbow and anchor
bolts in the form.
. 9.0 Steady the template assembly by
putting a 2” spacer between the
template and the top of the form.
Pour the concrete into the hole
and form - it will require
approximately ½ yard - screed
the concrete level with the top
of the form. Check to make
sure the template is correctly
orientated and centered. The
bottom of the anchor bolt
threads should be about ½”
above the top of the concrete.
Check to be sure the template is
“level” in two (2) dimensions.
Use a trowel and edger to finish
the concrete.
BE SURE THAT YOU HAVE
THE TEMPLATE PROPERLY
ORIENTATED IN RESPECT
TO “NORTH”. Refer to
FIGURE 4.
The template should have the
two (2) bolt holes, that are
parallel with one side of the
template, on the north side of
the base.
10.0 Wait 24 hours before removing
the concrete form. Wait 7 days
before mounting the weather
station to the base.
