The new Vectrino Profiler provides outstanding opportunities for high resolution observations of boundary layer dynamics and turbulence in the lab and the field. With the ability to profile three-component velocity (U,V,W) over a vertical range of 3 cm, with a resolution of 1 mm, and sampling rate of 100 Hz, the Vectrino Profiler allows new insight for a wide range of scientific studies.
New Hardware, Firmware & Software!
The Vectrino Profiler comes with completely new electronics, firmware, and software. For the firmware, adaptive pinging schemes have been added to minimize the effect of "weak spots" in the current profile. The new interface software provides enhanced capabilities such as real-time contour plots and energy spectra. The mechanical design was ported from the successful Vectrino single-point system and minimizes the flow interference from the probe onto the velocity profile. Because the Vectrino Profiler uses the same pressure housing and probes as the standard Vectrino, it can be easily integrated into your existing mechanical clamps and jigs.
Interleaved Bottom Detection
The new firmware allows 10 Hz bottom distance measurements to be interleaved with the high resolution velocity profile. The simultaneous measurement of velocity and bottom position makes the Vectrino Profiler an ideal instrument for measuring flow over clay, silt and sand. It also simplifies the data analyses by allowing all the velocity data points to be referenced to the bottom position.
