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 thegaugewell above the average local snow level. The exposure would be best if the tower wereto 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 thatfairlyis 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 of3/8 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.
