Laboratory - Shallow Water
[I-E]

MicroADV I want to make measurements in a laboratory. [change]
My research involves very shallow water (<5 cm). [change]

Depending on the scales of interest, one of our Acoustic Doppler Velocimeters (ADV) -- either the MicroADV or the ADV -- can be used in very shallow water. The MicroADV is capable of significantly better resolution in both space and time. The MicroADV probe needs to be within 20 m of your PC, while the ADV can be up to 30 m away. Distance (i.e., cable length) is important because of signal attenuation. There is less attenuation with the 10-MHz ADV as compared to the 16-MHz MicroADV.

2D ADV Probe To get measurements in water this shallow, a 2-D side-looking probe can be used. Only the horizontal flows will be measured, but the probes are capable of measurement in water as shallow as 2 cm.
