System Overview
The ADS ® RainAlert II

monitor measures rainfall using a tipping
bucket containing a funnel and a small tipping mechanism that can
collect a specific amount of rainfall. Once the tipping mechanism is
full, it empties and records that a tip has occurred. Typically, each
tip is equivalent to 0.01 inches of rainfall. The monitor records the
number of tips that occur over a specified period of time to
calculate rainfall amounts and to determine whether to initiate an
alarm during a rain event.
The monitor records rain data based on a defined time interval. The
monitor can store this data in memory and/or use the data to
generate an alarm. The monitor memory can store over 2 years of
data logged at a 15-minute sample rate. This data is available to the
user for collection, further processing, analysis, and reporting.
The RainAlert II monitor is designed for use in indoor or outdoor
environments. The monitor can be mounted to the wall of a
building indoors or outdoors. The monitor also can be mounted
onto a square, steel base plate and covered with a sun shield for
protection against the sun and inclement weather. The tipping
bucket can be mounted on a rooftop or other structure and secured
to either a base plate or directly to the top of the sun shield
protecting the monitor. Both the monitor and tipping bucket display
exceptional durability and accuracy, even under harsh and extreme
weather conditions.
Communication between the monitor and the user’s office or field
computer can occur over GPRS (remote, wireless communication),
