Principles of Operation - Currents

This section will provide you an overview of the principles of operation when using a Nortek instrument to measure currents. Most information found here is general and relevant for all different types of current meters and profilers.

Measurement principles

This sections describes the fundamental principles underlying the measurement of velocities using the doppler effect, the assumptions made to utilize this theory and the adjustable user input required. Additionally the available coordinate systems for data collection are described.

Range and range criteria

This sections described the physical and external limitations to your measurement range. It discusses means of estimating the achievable range when configuring the deployment as well as in post-processing.

Measurement area

This section describes the measurement volume in which a ADCP is collecting current data, as well as the user choices that can affect it.
