WaterLOG Products

WaterLOG Nile Radar Series

Nile Radar Series

Non-contact Water Level Sensor

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.

WaterLOG Storm 3

Storm 3 Data Logger

Our simple, reliable, and smallest data logger

The Storm 3 data logger incorporates a balanced set of inputs for analog, digital I/O and SDI-12 smart sensors to allow communication through cellular modems and GOES satellite. You'll love how easy it is to configure and log data using the browser-based graphical user interface (GUI) with all standard web browsers on PCs, tablets and smart phones. You can also view your password-protected and public data anywhere with internet access using our cloud hosted data collection solution Storm Central. Pair the Storm Central Data Collection Platform with the Storm 3 data logger and you've got one mean data-collecting machine that you can access anytime, anywhere.

Surface Water Monitoring System

Surface Water Monitoring System

Designed for quick and easy installation

SonTek RiverSurveyor

SonTek RiverSurveyor® S5 and M9

A new perspective to the notion of measuring open channel hydraulics

Using SonTek's exclusive SmartPulseHD®, multiple acoustic frequencies are fused with precise bandwidth control for the most robust and continuous shallow-to-deep discharge measurements ever. A deterministic microcontroller expertly apportions the proper acoustics, pulse scheme, and cell size to get the highest definition possible so you can focus on the measurement, not the instrument setup. The system even has a vertical beam for precise channel definition and it's all designed to work intuitively

SonTek-SL Series

SonTek®-SL Series

a simple way to measure water velocity and level in open channels

The SonTek-SL (affectionately known as the Side-Looker or "SL") has earned worldwide acceptance as a long-term monitoring solution. Now, with two new (3G) models turbo-charged by our proprietary SmartPulseHD®, the SonTek-SL features accessories, mounting options, software, and a variety of integration formats to ensure it fits your application.
