. Chapter 1: Introduction 1.1 General Description The RG-2500 Series consists of two high quality rain gauges, Models RG-2500RGand 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.
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.
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.
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.
4.4 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.
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. ge, replace the outer cover and funnel and Upon completion of testing and cleaning of the1ga 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.
