 Laboratory
Applications and Products
Though there had long been a need for a precise, 3D water velocity
instrument, it took until the introduction of the SonTek ADV to define the
future of how laboratory hydraulics measurements were to be made. Using a clever
combination of pulse-coherent Doppler technology with a multi-pronged bistatic
transducer, the SonTek corporation was born with the invention of the ADV.
Developed for the U.S. Army Corps of Engineers Waterways Experimental Station in
the early 1990s, the ADV has grown into a family of instruments that is no
longer limited to the laboratory. This family of products now includes the
MicroADV, the ADVOcean, the Argonaut-ADV, the Triton-ADV, and the FlowTracker.
 Because most laboratory users are interested in detailed fluid dynamic
phenomena, such as turbulence on small spatial and temporal scales, high
sampling rates and small sampling volumes are usually the most desirable
features. Other extreme measurement conditions such as very shallow or
slow-flowing water are also possible with the ADV. With an abundance of probe
options and configurations, both the MicroADV and the ADV give today's
laboratory user plenty of choices for their research experiments.

The MicroADV was invented on the foundation laid by the original ADV,
specifically with the laboratory user in mind. Using a 16-MHz carrier
frequency and significant hardware improvement, the MicroADV can maintain
similar accuracy while sampling at twice the rate (50 Hz standard, up to
200 Hz optional) and in one-third the sampling volume (< 0.1 cc) of the
original 10-MHz ADV. This makes the MicroADV the obvious choice for
turbulence research.

Having undergone many design improvements over the years, today's 10-MHz ADV
probe bears only some resemblance to the original one introduced in the
early 1990s. An integrated probe and conditioning module, a detachable
cable, and an optional ruggedized 10-cm probe make the 10-MHz ADV ideal for
a variety of field or lab work.
