I-Beam and Sled ADVM Mount
A 4" aluminum I-beam is used allow an ADVM to be raised and lowered on a stainless steel sled. The I-beam also serves as a pedestal mount for electronics housing.

ADVM Schematic
Top view of beam orientation and sample volume of a sidelooking ADVM. The ADVM-measured velocity used to index mean velocity is usually the sample volume x-component of velocity.

Example of Accoustic Profiler Orientations
Profilers measure velocities in uniformly-sized cells or bins along the acoustic beams (fig 1). By measuring velocities in a number of bins across a channel or vertically through the water column, these instruments produce horizontal or vertical water velocity profiles, hence the designation "profiler.
