Delivers extremely precise 2 or 3 dimensional velocity measurements (user selectable) in a defined free field. The ACM-PLUS uses the most accurate and stable current measurement techniques available today and is configured with standard features that are options on competitive instruments such as extended on-board data memory, fast download capability, high accuracy real-time clock, and high speed data sampling.
The unit’s compact size and light weight make the ACM-PLUS well suited for multiple meter arrays. Windows-based software for meter setup, data collection and data visualisation make the FSI ACM-PLUS very user-friendly.
The ACM-PLUS is available in either shallow-water or deep-water housings, see gallery for images for the mooring frames. The internal compass and tilt sensors to provide true current vector direction and the device may also be equipped with an optional pressure sensor, an optional Current, Temperature and Depth (CTD) module, and can be configured to log up to two analog inputs from external sensors (e.g., Dissolved Oxygen (DO), OBS, etc.).
The low power digital recorder and on board solid state memory make this system ideal for array based monitoring projects or spot measurements.
