| Abstract: | In water conservancy,various kinds of water-level measuring instruments are adopted to measure water-level change in time. Introduced in this paper is the float water-level measuring instrument in which a new optical coder is used as the acquisition device of the water-level signal. The basic principle and characteristics of the new coder are described. The hardware and software of the water-level measuring system are demonstrated in detail. Finally, the integrate precision of the presented system is given based on the precision experiment. |
