Using Orthogonal Combined Signals in Broadband ADCP for Improving Velocity Measurement
Journal of Marine Science and Engineering, 2020 Broadband Acoustic Doppler Current Profiler (BBADCP) is a widely used technology in velocity measurements. To adapt to the varied water environment and different measurement requirements, flexible tuning of transmitted signal parameters will improve the ...

Velocity Calibration of Doppler Current Profiler Transducers
Journal of Marine Science and Engineering, 2020 Doppler current profilers are used in oceanography to measure oceanic circulation but also in hydrology to calculate the flow of rivers. They allow the retrieval of water mass profiles in terms of velocity and direction.

Japan Tsunami Current Flows Observed by HF Radars on Two Continents
Remote Sensing, 2011 Quantitative real-time observations of a tsunami have been limited to deep-water, pressure-sensor observations of changes in the sea surface elevation and observations of sea level fluctuations at the coast, which are essentially point measurements ...

Traveling-Wave Electrokinetic Micropumps: Velocity, Electrical Current, and Impedance Measurements [PDF]
Langmuir, 2008 An array of microelectrodes covered in an electrolyte and energized by a traveling-wave potential produces net movement of the fluid. Arrays of platinum microelectrodes of two different characteristic sizes have been studied. For both sizes of arrays, at low voltages (
