Improved accuracy and performance for flood warning systems
Overview
The AL200 is an ALERT2 encoder and modulator that supports ALERT2 and ALERT-concentration services. It meets the ALERT2 standards maintained by National Hydrologic Warning Council (NHWC) and ALERT Users Group (AUG). ALERT2 improves the accuracy and performance of flood warning systems and software, by providing you with faster data transfer, forward error correction, and a TDMA architecture.
With integrated sensor inputs, the AL200 allows you to create a minimal ALERT2 transmitter/station, decreasing the cost of a typical flood warning system. Combining the AL200 with a Campbell Scientific data logger provides enhanced sensor support, user-defined logic and control, and data logging capabilities.
