Project: Rapid Deployment Gage - Version 4
RDG-4 deployed at DORAN SLOUGH AT COUNTY ROAD 158 NEAR DORAN, MN
The Rapid Deployment Gage – Version 4 (RDG-4), is a self-contained, lightweight system designed to install very quickly and easily in advance of a flood or other emergency condition. These units can also serve as quick temporary replacements for gages lost or damaged during such events. The design allows one person the ability to deploy the unit in approximately 30 minutes or less. The system consists of a GOES transmitter, data logger, satellite antenna, battery pack and GPS receiver/antenna contained within a single enclosure. The only external devices in the system are the pressure transducer, interface box, a solar panel and inter-connecting cables for those devices. The entire package weighs less than 25 pounds. The small physical footprint of the system allows for minimal visual impact on the environment.
