Wireless, Battery-Powered Rain Gauge Recorder


When you combine the Trimble Telog RG-32A rain gauge recorder and Telog Online, or Trimble Water Unity cloud solutions, you have a powerful system of wireless water infrastructure monitoring that is consistently delivering real-time data from the field straight to your desktop. Imagine.....all your data on one platform straight to your computer

Wireless Communication
The power of every 32 series recorder from Trimble Telog is wireless data transfer capability. Using cellular technology enables unmanned monitoring of remote sites as well as instant updates and alarm notifications. The RG-32A uses
a low power, LTE/Cat 1 cellular communication modem certified on multiple cellular systems. This ensures maximum coverage, reliability of service and alignment with cellular carriers technology roadmaps. 

Collecting Data
The Trimble Telog RG-32A may be configured to call its server 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 80,000 interval totals before overwriting the oldest data.

The cellular modem, antenna, process signal conditioning, data recorder and battery are integrated into a small IP68 rated enclosure for a combined weight of 2.5 pounds and measuring 4”L x 4”W x 3”H [102mm L x 102mm W x 76mm
H]. The Trimble Telog RG-32A is small enough to install on the pole or mounting platform attaching the rain gauge. Because the antenna is enclosed within the Trimble Telog RG-32A, the only connection required is the rain gauge.

Battery Powered
Powered by a single user replaceable BP-4 lithium battery pack, the Trimble Telog RG-32A 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 the cloud or to a central host computer. The Trimble Telog RG-32A can operate up to five years making on average one call per day.

Software Support
The Trimble Telog RG-32A is compatible with all Trimble Telog software applications, including Trimble Unity,Telog  Online (cloud), Telog Enterprise and Telogers for Windows application software. This ensures that utilities have a complete solution addressing all their remote monitoring requirements delivered in a manner that suits
each individual utility’s operations and IT needs.
