velocimeter

[‚vel·ə′sim·əd·ər]
(engineering)
An instrument for measuring the speed of sound in water; two transducers transmit acoustic pulses back and forth over a path of fixed length, each transducer immediately initiating a pulse upon receiving the previous one; the number of pulses occurring in a unit time is measured.

A Nortek Vector velocimeter measured three components of velocity relative to the float at a point about 1 m below the float's center of buoyancy: that is, effectively measuring 1-m vertical shear.
We determined hydrodynamic characteristics of the artificial stream by measuring the flow with an acoustic doppler velocimeter (ADV, Nortek U.S.A.) at three down current positions (relative to the odor source, 30, 60, and 90 cm) within the working section of the channel.
He holds several patents in the area of flow meters and has been developing a Doppler global velocimeter for many years.
He gathered the speed values at different depths in the networked points at the junction by Acoustic Doppler Velocimeter and then he calculated the average turbulent speed and intensity from the time series in different places.
Water velocity was measured with an Acoustic Doppler Velocimeter (SonTek ADVField) to characterize the flow at the height of the female urchin when the urchin was not present (0.04 m above the substrate).
In January 2003, a Nortek acoustic Doppler velocimeter was placed in the middle of a seeded mussel raft at a 5-m depth for a period of 5 days.
