Z1 and Z2 velocity

Posted by Khalid Al-Asadi at October 13. 2013

As I understood from the vecrtino II manual that there is only one velocity profile in x and z directions and two velocity profiles in y-direction. From the measurements, I found that there are two values for velocity in z-direction (Z1 and Z2). What doed this mean?

 

Thanks

Hi Khalid:

 

   Three transducers are needed to produce the X,Y,Z components of the velocity.  With four transducers, this gives us the capability to provide two independent measurements of the vertical velocity.  These are typically used to assess data quality.  See, for example,  http://www.nortek.no/en/knowledge-center/forum/vectrinoii/761683437.

The link has a some strange characters attached to it for some reason (.%A0). 

Here is the same link plus another one that may be useful. The link should be the same as the text shown.  If it isn't just delete the extra characters.
