Hello Eco Community!

We recently received the following questions from an Eco user so I thought I'd share them here in case others have similar questions (slight rewording done for clarity).

1) How many current velocity measurements does the Eco make in one session?

2) What velocity value does it record in one session (average or maximum)?

3) Time operation (battery/deployment life) at the same interval differs in depth, why in a deeper place of 20 m the device will work longer in contrast to setting it at a depth of 8 meters (the difference in working time is about 30 days)?

4) Will the device record speed measurements, if run it in a test version in the air (in the laboratory)?

  And here are the answers to the questions :-)

  1) The averaging interval is automatically set in order to provide enough pings such that a 1 cm/s precision (or better) is achieved under all conditions.  This is a function of the user-selected measurement interval and the deployment site's depth.  The number of pings used can be as few as about 12 pings and as high as several hundred pings.  In terms of time, this can be as short as about 1 minute and as long as about 10 minutes.

  2) The value reported is the average over the user-selected measurement interval.

  3) This questions as answered in an earlier post, so suggest reviewing that: https://support.nortekgroup.com/hc/en-us/community/posts/4405120184338-Battery-Duration

  4) No.  Although the Eco will transmit acoustic pulses and measure all its ancillary sensors, it will detect it is in air and therefore the automatic QA/QC will invalidate all the data.
