Tide staff system

摘要

The present invention relates to a segmented cylindrical tide staff system 11 for erection at remote areas for dynamic calibration of electronic tide meters and computer models of tides, said tide staff system consisting of plurality of cylindrical tubes 12, said cylindrical tube being coupled to a flange 13 at its end through a circular orthogonal hole 20 drilled on a flat surface of the flange, said flange being provided with plurality of equally spaced slots 15 drilled on the flat surface of the flange, an outwardly protruding tide indicating arm 14 being mounted on the flange wherein said tide indicating arm consists of two mutually orthogonal planes 22 and 23, wherein plane 22 is perpendicular to the axis of the tide staff and plane 23 is parallel to the axis of the tide staff, said perpendicular plane 22 being provided with a mounting terminal 21 and a circular hole 27 and said parallel plane being partitioned into two compartments 24 and 25 by a separating line 26 thereby permitting indication of tide reading in more than one language, including a vernacular language and two or more cylindrical tubes being coupled to each other through slots 15 using coupling means.
