Nile Radar Series

WaterLOG Nile Series Radar Sensors

NEW Nile Series 502/504/517 models! Designed for non-contact water level measurement, the WaterLOG Nile Series (502/504/517) combines high accuracy with an out-of-the-box measurement range of up to 70 m. The rugged, innovative design was inspired for installation on a bridge or other structure over the water—making this series ideal for sites that may have ice or other instrument-damaging debris. Its reliable interface and simple SDI-12 communication ensure seamless integration with current water monitoring stations. With three models to choose from, the Nile Series is sure to meet your water monitoring needs.
