iGage Automated River Gages

The National Oceanic and Atmospheric Administration (NOAA) intends to negotiate and award a purchase order on a sole source basis to BeadedStream for the provision of automated river gage sensors. The sensors must be self-contained units with an integrated river stage sensor, weigh less than 10 lbs, and have an integrated battery and solar power supply. The river gage accuracy must meet USGS requirements and transmit data via satellite telemetry. The key requirements for the automated river gages include: • Self-contained with integral DCP, battery, solar panel, stage sensor • Satellite iridium SBD telemetry (to work with existing iridium contract) • Lightweight (less than 10 lbs) • Measurement range of 30 m with an accuracy of 0.01 feet
