RG-32 Wireless, Battery-Powered Rain Gauge RTU

Continuously monitors output of a tipping bucket rain gauge
Cellular communication
Integral antenna
Battery powered
Small size
Five year operating life

Telog’s RG-32 wireless rain gauge establishes a new standard in low power, low cost wireless communication RTUs for rain gauge monitoring. Powered by a single user replaceable D cell lithium battery, the RG-32 continuously monitors the output of a tipping bucket rain gauge collecting rainfall data in user defined time increments then transfers the data automatically over a cellular network to a central host computer. The RG-32 can operate up to five years making on average two calls per day.

Wireless Communication

The RG-32 is available with a choice of three wireless communication technologies:

1xRTT CDMA cellular networks
GPRS GSM cellular networks

Packaging

Packaged within a 6.5”x3”x2” NEMA 4x rated environmental enclosure, theRG-32 is small enough to install on the pole or mounting platform attaching the rain gauge. Because the antenna is enclosed within theRG-32, the only connection required is the rain gauge.

Collecting Data

The RG-32 may be configured to call its host application on a schedule(e.g. once per day; every four hours, etc.) and/or on alarm (e.g. in response to a major rainfall event). Data may be stored in the recorder at user defined intervals (e.g. five minutes, one minute etc.) without concern for data loss because the recorder will store over 80,000interval totals before overwriting the oldest data.

Data Management Software/Service

The RG-32 is supported by Telog Enterprise and Telogers for Windows host application software. Telog also offers a Data Management Service for users who prefer to outsource the computer data collection and management tasks providing end-use information on a secure website.
