Chapter 1
Introduction
Thank you for purchasing Nortek’s Vectrino velocimeter! Your Vectrino has
been designed to provide you with many years of safe, reliable service.
The Vectrino is a high-resolution acoustic velocimeter used to measure
turbulence and 3D water velocity in a wide variety of applications from the
laboratory to the ocean. The basic measurement technology is coherent
Doppler processing, which is characterized by accurate data and no
appreciable zero offset.
Getting Started
This guide in combination with the Quick Start guide which is part of the
Help function in your Vectrino software, will help you getting started with
your Vectrino. As initial preparation for using your new Vectrino
velocimeter, we recommend the following steps:
1Verify that you have received all parts (see next page).
2Install the Vectrino software on a computer (see chapter 5, Software).
3Perform a functional test of your new Vectrino (see chapter 7, Test and
Verification).
4Mount the Vectrino in accordance with the guidelines (see chapter 6,
Mounting Guidelines).
