"A current meter is designed to directly measure the true magnitude and direction current motion in any water environment using two pairs of titanium electrodes located symmetrically on the equator of the sensor. An internal flux-gate compass provides heading information, used to reference current direction to magnetic North or, for fixed installations, the instrument may be operated in an X-Y orthogonal mode whereby the current vector can be referenced to a landform or structure. It can be deployed upto depths of 6000m. Further information may be found on the BODC document server at URL http://www.bodc.ac.uk/data/documents/nodb/40555/. The \"A\" designation indicates advanced current measurement with adaptive sampling as standard. The \"D\" indicates a pressure-hardened casing."@en . "2010-05-18 16:10:58.0" . "SDN:L22::TOOL0153" .
