Acoustic Doppler Velocimeter

Precise measurements of 3-D fluid flow

( Ӱ)


ADVLab for Lab





The ADVLab is designed for use with a desktop PC in a laboratory setting. It is very simple to setup and operate, the data are stored directly to hard disk, and the power is supplied from the PC.

The standard unit is delivered with a 5cm down looking sensor mounted on a rigid 40cm steam.

The standard cable length to the PC is 10 meters. Analog outputs for use with a secondary data

acquisition system are optional.
