DESCRIPTION:

The Tipping Bucket Rain Gauge - 2400 Series provides state-of-the-art technology for flood warning and rain monitoring applications. The Tipping Bucket Rain Gauges consist of a 12 inch (30.5 cm) diameter housing, a 12 inch (30.5 cm) anodized funnel, a 12 inch (30.5 cm) anodized debris screen, a 4 inch (10.2 cm) stainless steel screen, and tipping bucket mechanism. The Tipping Bucket Rain Gauge mechanism is available in 1 mm or 0.01 inch tip increments. The Tipping Bucket Rain Gauge's mechanism is mounted on an anodized aluminum base section with an integrally mounted bulls-eye level that uses spring-tensioned adjusters for accurate, set-and-forget operation. The Tipping Bucket Rain Gauges come complete with 25 ft (7.6 m) signal cable and 5 Pin MS connector.

Water is directed into the Tipping Bucket Rain Gauge's mechanism which is adjusted to tip when 1 mm or 0.01 inch of rain is collected. As the Tipping Bucket Rain Gauge's bucket tips, it causes a magnet to pass over a sealed reed switch, closing the switch momentarily. The contact closure is then counted by the Tipping Bucket Rain Gauge's circuitry in your data collection equipment. Measurement accuracy is ±1.5% at a precipitation rate of 0 to 3.6 inches per hour and ±3% for above 3.6 inches to 6 inches per hour. Water is discharged through drain holes at the base of the Tipping Bucket Rain Gauge housing. The Tipping Bucket Rain Gauge's drain holes are protected by screens to prevent insect entry.

An optional Tip Rate Compensator (Model 2400-50) can be added to the Tipping Bucket Rain Gauge to provide a typical accuracy specification of 0.5% over any range of rain rates. The compensator mounts directly on the Tipping Bucket Rain Gauge’s input connector when used in conjunction with a data transmitter, such as the ALERT/IFLOWS Data Transmitter.

The Tipping Bucket Rain Gauge - 2400 Series is designed to fit on a standpipe assembly, but can easily set up with the roof or pole mounting option.
