Suber SLS21 vector-averaging current meter
accepted
A current meter fitted with a Savonius rotor magnetically coupled to a reed switch counter, a vane on tungsten carbide bearings magnetically coupled to a compass and solid-state crystal clock. Current vectors were continuously measured and then averaged after a specified time interval (generally 10 minutes) by an on-board minicomputer to produce the logged data values. Accuracy was 2 per cent for speed, 4 degrees for direction and 2 seconds per day for the clock. Casings were available for operating depths of 1000m, 3000m and 6000m.More information may be found in http://www.bodc.ac.uk/data/documents/nodb/19202/
