The OTT SVR 100 Surface Velocity Radar Sensor is designed for measuring flow in open channels and rivers. The sensor is compatible with NexSens X-Series data loggers utilizing the SDI-12 communication protocol and sensor interface. Parameter data is transmitted, in real-time, at a user-specified interval (e.g., 10 minutes) to the NexSens WQData LIVE Web Datacenter. There, […]

CB-40 Data Buoy Overview
The CB-40 data buoy is a simple, compact platform for deploying water quality sondes and other instruments that integrate power and data logging. It features an integrated 4″ diameter stainless steel slotted instrument pipe and supports mounting of an optional 1-3 nautical mile light for deployment in navigable waters. Key Components and Definitions Buoy […]
CB-250 Data Buoy Overview
The CB-250 data buoy strikes a balance between compact and easy to deploy, yet buoyant and powerful enough to be deployed in larger water bodies including lakes, rivers, coastal waters, harbors, estuaries and other freshwater or marine environments. Like all solar-powered NexSens CB-Series data buoys, it is a highly customizable platform that may be configured […]
Using NexSens Electronics in CB-Series Data Buoys
Although users may provide their own electronics, including data loggers, modems, and batteries, many CB-Series data buoys are delivered as complete, plug-and-play system packages with a NexSens data logger as the central component of the system. Data Loggers NexSens offers four different data logging systems for buoy deployment, all of which are based on the […]
CB-Series Data Buoy Planning & Precautions
Buoy deployments are usually complex operations that involve many elements including sensors, data loggers, mounting hardware, and mooring equipment. Careful planning and precautions are essential to the success of a buoy project, not only for system operation and data collection but also to ensure the safety of project personnel and minimize the risk of damage to […]
CB-150 Data Buoy Overview
The CB-150 data buoy is a compact buoy platform designed for smaller water bodies, portable or short-term deployments, and applications requiring small, power-efficient sensors. It is ideal for deployment in lakes, rivers, coastal waters, harbors, estuaries, and other freshwater or marine environments. Like all solar-powered NexSens CB-Series data buoys, it is a highly customizable platform […]
CB-Series Data Buoy Ballast Weight & Stability
Ballast weight may be needed to prevent overturning a buoy system and ensure stability in the water. The center of gravity of NexSens data buoys is near the water surface without instruments connected. Therefore, any top-side weight added above the water’s surface (e.g. navigation aids, sensors, sensor mounts) must be appropriately counterbalanced by ballast weight below […]
