1. Overview The RGTE series of Tipping Bucket Rain Gauges is a freestanding receptacle for measuring precipitation. It contains an open top, which allows precipitation to fall into the upper portion, called the collector. The collector funnel is made of gold-anodized aluminum.
RGTE Tipping Bucket Rain Gauges 2. Installation The rain gauge has been tested thoroughly and fully calibrated at the factory, and is ready for installation. Unpack the rain gauge. 2.1 Physical Installation A clear and unobstructed installation location is necessary to realize accurate rainfall readings. The rain gauge is designed to be mounted in one of three ways.
RGTE Tipping Bucket Rain Gauges Drill three 1/4" diameter holes in the concrete pad using a masonry bit. A template is provided in Figure 2. NOTE The template might not reproduce to scale when printed. It is recommended that the information in the template is used to prepare the template that will actually be used or that the template provided be scaled accordingly.

RGTE Tipping Bucket Rain Gauges Install three 1/4" screw plug inserts into the holes just drilled. Position the rain gauge feet over the holes. Use washers under the feet to level the rain gauge, referring to the bubble level to make sure the rain gauge is level. Secure the rain gauge with corrosion- resistant #6 sheet metal screws.
RGTE Tipping Bucket Rain Gauges 2.1.2 Mast Mounting Use T-bolt band clamps or U bolts to secure the rain gauge to a mast as shown in Figure 4. When securing the rain gauge to the standard 2.5" NPT mast, keep in mind that the outside diameter of the mast is 73 mm (2.875") and the clamp should have a circumference at least 20 mm (0.75") more than the circumference of the mast to hold the...
RGTE Tipping Bucket Rain Gauges 2.1.3 Tower Mounting The M488169-01 Tower Mounting kit is available to mount the rain gauge on a tower as shown in Figure 5. Figure 5. Tower Mounting Use the U bolts and the associated nuts and washers to attach the crossarm to the tower. If a level is available use it to level the crossarm before tightening the nuts.

RGTE Tipping Bucket Rain Gauges Use the two 3/8-16 × 2.5 bolts and the 3/8-16 nuts and washers to secure the mounting plate to the crossarm. Position the rain gauge feet over the mounting plate to line up the feet with the corresponding mounting holes.

RGTE Tipping Bucket Rain Gauges Insert flat #6 washers as needed between the rain gauge feet and the mounting plate to level the rain gauge, referring to the bubble level to make sure the rain gauge is level, Secure the rain gauge to the mounting plate with the 6-32 pan head screws and flange locknuts.
RGTE Tipping Bucket Rain Gauges 2.2 Connections Once the rain gauge has been installed physically, remove the screen and the gold funnel to observe the black tipping bucket. The tipping bucket should not be held in a dead center position by the magnetic attraction of the bucket magnet and the magnetic switch.
RGTE Tipping Bucket Rain Gauges 3. Maintenance Normal maintenance is limited to cleaning debris out of the orifice. Use the precipitation screen during periods of rain to prevent insects and stones from entering the rain gauge, but remove this screen during the winter. When the rain gauge is installed as part of an AWOS, special maintenance procedures are required, as described below.
Use the bubble level to make sure the rain gauge is level when it is returned to the field. ADB Safegate offers the Model 60103 Precipitation Gauge for checking the rain gauge calibration in the field. A measured amount of water, equal to 200 tips of the bucket assembly, is directed into the rain gauge at a constant rate of 2 inches per hour.
