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.
