Chapter 1: Introduction

1.1 General Description

The RG-2500 Series consists of two high quality rain gauges, Models RG-2500 and

RG-
2500-12. Model RG-2500 features a standard eight-inch diameter orifice, while the Model
RG-2500-12 has a twelve-inch diameter orifice. Both gauges have been designed with high

grade materials and have been built to provide years of trouble-free operation.

Each of the two gauges consists of a main collection funnel, an outer cover, an internal
funnel, a tipping bucket and magnetic switch assembly, a base, and mounting feet with
leveling adjustments.

Electrically heated versions of both gauges can be provided for use in cold climates, for

measuring frozen precipitation such as snow and sleet. The electrically heated versions
include the features listed above plus a heater element, a thermostat, a fuse holder and fuse,

and associated wiring and terminal blocks. The model numbers for the heated rain gauges are
RG-2500E and

RG-2500E-12.

Chapter 2: Installation

2.1 Site Requirements

The location of the rain gauge is very important to the successful operation of the instrument.

The most accurate measurements are made in relatively sheltered areas protected from
gusting and turbulent winds. Openings in orchards or a grove of trees offer the best exposure
for the rain gauge. Fences and other structures can help serve as a wind break as long as

they are not too tall. In areas that are open with no nearby structures, a wind screen such is

recommended to protect against wind effects.

Generally, the heights of objects near a rain gauge should be proportional to the distance

away from the gauge. The distance of a nearby object should always be at least twice the
height of the object above the gauge.

Wind effects on catch losses are more pronounced during snow storms than during a rain
storm. A wind screen is generally not used at locations where snowfall constitutes less than
20% of the mean annual precipitation.

Good locations do not always remain free of obstructions. Vegetation can grow quickly,
changing an excellent exposure into a poor one. Sites should be inspected regularly in order
to properly maintain the exposure of the gauge.

In locations with heavy snowfall, the gauge should be mounted on a support or tower to
place the
tower were

gauge well above the average local snow level. The exposure would be best if the

to

be located among trees of the same height as the tower.

2.2 Installation

OMEGA@ rain gauges are shipped as a complete assembly with no additional assembly
required. ‘The gauge, however, should be installed onto a platform or foundation that is

fairly
close to being level to minimize the amount of adjustment required after the gauge is
mounted. Each gauge is equipped with three mounting brackets that also serve as feet. Each
foot has a mounting hole with a diameter of

3/8 inches. The holes in the feet should be
matched to anchor bolts located in the foundation or on the platforms. for severely tilted
foundations, use a set of three hex nuts on each bolt to provide leveling and locking of the

rain gauge onto the foundation. For slightly tilted foundations, use the adjustable leveling

knobs above each foot to level the gauge. An internally mounted spirit level may be used to

assist in the leveling process. A rough level can be taken by placing a carpenter ’s level

across the top of the gauge funnel. Flat washers may be used as shims to help correct large
leveling differences. Place the shims under the mounting feet. A lock washer and a hex nut
should be used to secure the gauge onto the anchor bolts. Some correction of the level may
be necessary after tightening the hex nuts.

2

The leveling knobs located above the mounting feet are secured using

allen

head set screws.
These set screws must be loosened before the knobs can be moved. The set screws are
accessible from the sides of the base. Re-tighten the set screws after leveling the gauge to
help ensure that the level adjustment will not shift due to loose screws.

The gauge may be installed with the outer cover on or with it removed. Three screws hold
the outer cover in place. Take out these three screws to remove the cover. Carefully remove
the cover, avoiding hitting any of the internal rain gauge parts. Some of the moving parts are
tied down to prevent movement and possible damage during shipping. Remove any tape,
plastic ties, foam inserts, or other objects used to keep the tipping buckets from moving. The

bucket assembly should move easily with the packing materials removed.

Chapter 3: Operation

The rain gauge operation is relatively simple.

As rain is collected by the eight-inch diameter
orifice, the rain drops are directed down through the funnel and into the bucket assembly. As
soon as the bucket has collected enough rain to represent 0.01 inches (or 0.25 mm) of rain,

the bucket tips. The rain drains out through the drain collection tubes and the magnet is

moved past the reed switch. The reed switch closes momentarily, making an electrical
contact that is used in conjunction with electronic counting and recording instruments.

Chapter 4: Calibration

4.1 Factory Calibration

Each rain gauge is thoroughly tested before being shipped to the customer. A measured
amount of water is passed through the rain gauge to give an expected number of counts
according to the diameter of the orifice. The bucket calibration posts have screws that are
adjusted until the correct number of counts are achieved with repeated testing. The exact

number of counts or nearly the exact number are recorded for each gauge. As long as the
number of counts is within the specified accuracy of the gauge, the calibration will be

accepted. The calibration of the gauge should not change during shipping unless the gauge

becomes damaged. Checking of the gauge calibration may be made after the gauge has been
installed to ensure the accuracy of the data.

4.2 Calibration Procedure

The rain gauge calibration may be checked using a graduated burette or cylinder. Wet the
gauge thoroughly allowing water to flow through the gauge before beginning the test. The
wetting of the gauge helps compensate for water that may adhere to

portions.of the gauge

causing some error in the counts.

3

Allow a measured amount of water to flow into the gauge at a specified rate. Refer to the
table shown below. The tipping bucket should begin tipping and will give the number of tips
calculated. The tips may be counted by listening to the bucket assembly and manually
tabulating the count or by using the electronic monitoring equipment that is to be connected
to the rain gauge during its normal operation. Should the gauge appear to need adjustment,
make the adjustments in small increments and retest each change at least three times.

Use a flow rate of 1 ml per second to avoid over filling of the buckets and loss of water due

~3%

to splashing. the desired accuracy is

of the volume at 1 to 6 inches of precipitation per
hour. Best results are obtained by taking a multiple of the volume of water and counting a
number of tips. For example, the 0.01 ” calibration at 100 counts requires 824 milliliters of

water.

4.3 Field Calibration

To verify the rain gauge calibration after the gauge has been installed, best results may be
obtained using the calibration bottle. The bottle may be filled to the specified level and then
placed into the funnel of the gauge. While the bottle slowly empties the water into the funnel
other tasks may be performed if necessary. If the calibration bottle is not available, use any
calibrated measuring device and slowly pour the water into the gauge. Keep track of the
bucket tips either manually or through the use of the electronic monitoring equipment. For

45%

field testing methods, use an expected accuracy of

since the control of the methods is
not as good as when the testing is done in the laboratory. The total number of tips should
equal the amount of water poured into the gauge, divided by the calibrated number of tips
per the number of milliliters of water shown in the table. For example, a quart of water is

fof

equal to 946.3 milliliters. So for a 0.01 ” calibration, the number of counts

t

water should be 946.3

8.24 = 114.8.

Adjustments

Should the calibration of the rain gauge appear to be incorrect and in need of adjustment,
change the heights of the two calibration posts adjustment screws. To change the screw
heights, loosen the nut on the top of the post that locks the screw into place. Rotate each
screw by a small amount only and recheck the calibration for the new screw positions.
Empty all water from the buckets but do not dry off the buckets. The exact amount of water
needed for a single bucket tip may be added into a bucket to see how closely the calibration
post screw may be to the position needed for the bucket to tip. After obtaining this point of
adjustment, tighten down the locking nuts on the calibration posts screws and test the gauge
using a large amount of water at the proper flow rate and count the total number of tips.

The calibration post screws should be adjusted upward whenever the amount of water needed

to cause the bucket to tip is more than the amount shown in the calibration table. Whenever
less water than the amount in the table causes the bucket to tip, the screws need to be
adjusted downward. The two sides of the bucket assembly should generally be at about the
same calibration adjustment. There may be situations where one of the bucket calibration

post screws has moved and is off more than the other screw. In this situation the single tip

amount of water calibration method may be better for correcting the one side of the bucket to
match the other side more closely. Do not dry the buckets during the adjustment procedure.

Carefully tighten the locking nuts on the calibration post screws after completing the

adjustments. Recheck the calibration to ensure that the screws have not shifted as the nuts

were tightened.

Chapter 5: Maintenance

Annual maintenance of the rain gauge is recommended. Cleaning of the gauge more often
may be necessary in areas where there is a lot of leaves, dust, and other debris that falls into
the gauge. Cleaning includes removal of the outer cover, rinsing and drying off of the
buckets, cleaning of the drain holes, and removal of debris from all of the screens. the outer
and inner funnels should also be rinsed and dried off to remove dirt, dust and insects.

The gauge calibration should be tested during the maintenance procedure and adjusted if
necessary. If there is a regularly scheduled maintenance of the gauge on a monthly basis, the
calibration can be tested less often.

At least once a year, or if possible, after six months of heavy operation, a drop of light

machine oil should be placed onto the bearings. Do not over-oil and wipe off any excess oil.

The electrical output of the gauge should be tested to ensure that the magnet and switch
assemblies are still functioning. The switch used in the gauge is a momentary contact,

normally open, single pole switch. Test the switch using an ohmmeter, buzzer, or counter, or

5

by observing the data of the monitoring

equipmen

normally connected to the rain gauge.

Manually move the bucket assembly and look for he switch closure.

1

Upon completion of testing and cleaning of the ga

ge, replace the outer cover and funnel and
recheck the level of the gauge using a carpenter ’s level across the top of the gauge. Adjust
the leveling knobs at the mounting feet if the level is out of adjustment.

Replace or repair any of the gauge components that appear to be damaged or are not
functioning properly. The outer funnel should be replaced if the rim has become dented or
bent. Repaint the outer cover as needed. Replace any hardware that is missing or has become
rusted and corroded. Inspect the signal and any power cables for signs of wear or damage
that may expose the wires. Replace the cables as needed. Use wire ties to secure the cables
to prevent damage from high winds. For best results, use conduit to protect the cables.

Chapter 6: Troubleshooting

Failure of the rain gauge to operate usually is the result of loose wiring. Inspect the cable
connections to ensure the connections are solid and are correctly made.

Inspect the motion of the bucket assembly to ensure that the buckets move smoothly and
without any interference. Check the magnet to see that it passes over the switch without any
physical contact and that the switch closes when the magnet passes over it. Should the bucket
motion appear to be sticky, remove the bearings and inspect them for wear. Annual
replacement of the bearings may be necessary in areas where there are high amounts of rain.

Check the inlet funnel and funnel screens for blockage whenever the rain gauge operation
appears to be low or missing. Also inspect the drain tubes for debris that may interfere with
the bucket motion.

Whenever the rain gauge output appears to be too high, check to ensure that the gauge is still
level and recheck the calibration.
