FSI - Model 2D ACM -2-Dimensional Current Meter
A compact, cost-effective meter with vector averaged current speed and direction. The Falmouth Scientific, Inc. 2-Dimensional Acoustic Current meter represents the state of the art in acoustic current meter design. Utilizing ultra-low-power solid-state design, the 2D ACM offers a very compact, lightweight measurement tool capable of high-accuracy horizontal current measurement. With internal data logging capability, long- term battery operation, internal electronic compass and tilt sensors, the 2D ACM is well suited for a broad variety of measurement applications.
The instrument is available in either shallow-water plastic, or deep-water titanium housings. The 2D ACM also has the capability of adding a CTD module and can log up to two analog inputs from external sensors (e.g., DO, OBS, Fluorometer, Transmissometer).
