Nortek’s tech expert David Velasco outlines the three main methods that exist to measure water speed with acoustics, and explains why the Pulse Coherent Doppler method must be used thoughtfully if you want accurate and precise data.
ADCPs are great for current measurements, but can they be improved for sediment measurements? Absolutely! In this article you will find out how the Signature1000 echosounder improves two important aspects of your sediment measurements.
What it is? An online measurement is real-time telemetry (or transmission) of sensor data to either a secondary telemetry system (i.e. satellite or GSM modem) or directly to a PC for real-time or near real-time display or storage.
Adding sophisticated Attitude and Heading Reference Sensors (AHRS) inside our series of Signature ADCPs is helping scientists and ocean engineers obtain reliable data from ADCPs mounted on surface buoys.
Although Nortek’s Vector velocimeter is more accustomed to highly energetic environments such as those found in surf zones, researchers in Japan have shown that it is equally at home in much more gentle – yet just as challenging – condition...
