The following article provides information on the proper settings required for communication between a Nortek AWAC Current Profiler and an X2 data logger. Advanced information describes the NMEA messages and parameters recorded from the sensor by the X2 and includes troubleshooting procedures for common error codes. Nortek AWAC Current Profiler Setting Requirements […]
TriOS UV Nitrate Sensors are in-situ UV photometers that measure nitrate in lakes/rivers, drinking water, and wastewater applications. Nitrate is measured using the common principles of UV optical absorption utilized in laboratories worldwide. The sensors are compatible with X-Series data loggers over the RS-485 sensor interface using the Modbus-RTU communication protocol. Below is information on […]
The table below indicates the minimum recommended buoy ballast weights for each NexSens data buoy, assuming no additional topside weight and calm environmental conditions. Included instrument cages mounted to the buoy frame help stabilize the buoy and provide a deeper location for mounting additional weight. The small model instrument cage (10 lbs.) is included with […]
The following buoy storage requirements are required when storing a CB-Series data buoy with an X2-CB data logger: Storage Requirements Store the buoy in a dry environment that is kept above freezing. A climate-controlled location may be necessary. Extremely cold temperatures can negatively impact the performance of the batteries. Cold or excessively fluctuating storage temperatures […]
The Nortek Signature Series sensor is a high-performance acoustic doppler current profiler (ADCPs) used for measuring wave current velocity (via multiple cells), current direction, water temperature, and pressure. Configure Deployment Template Nortek’s Signature Deployment software must be used to configure a Signature Series sensor for use with an X2 Data Logger. Download and install […]
CB-Series Buoys supplied with a CB-PTL Pass-Through Lid for integration of user-supplied electronics include a UW-6 power bulkhead connector (UW6-BULK) port on the lid. The UW6-BULK connects to the solar tower on the outside of the buoy and has bare wires with Molex connector on the inside of the data well. Information regarding the port […]
Flood warning systems are designed to help improve warning of flood and weather events. These systems help give early warning for the public and local governments based on local measurements in real time.
Dredging done correctly doesn’t hurt water quality, and can yield positive environmental results. However, ensuring these good results demands monitoring for contaminant release, sediment resuspension, and other water quality issues.
Coastal buoy monitoring systems, which are subjected to harsh and unpredictable weather and other forces, are simple to use and promise highly accurate performance despite punishing conditions.
Real-Time Water Temperature Measurements The NexSens TS210 Thermistor String provides high-precision temperature measurements for profiling in lakes, streams and coastal waters. It features an integral titanium thermistor secured and epoxied in a protective housing for underwater deployments. TS210 strings integrate with NexSens X-Series data loggers using the Modbus communication protocol and RS-485 sensor interface. A […]
