Recording current meter with box, designed by Jonas Ekman Fjelstad and made by Bergen Nautik, Bergen, Norway, 1953.
This device was designed in 1949 by the Norwegian oceanographer Jonas Ekman Fjeldstad. It enabled a series of readings of the velocity and direction of currents to be taken. The meter incorporated a metallic tape, onto which the number of counted propeller revolutions, and the compass direction of the alignment of the instrument, was stamped each time that a messenger weight was released down the line to which the device was attached.
