UNDERWATER ENVIRONMENT MEASURING APPAPRTUS AND UNDERWATER ENVIRONMENT MEASURING METHOD IN USING SAME

摘要

PURPOSE: An underwater environment measuring apparatus and an underwater environment measuring method thereof are provided to simultaneously measure water level of underwater environment to reduce the risk of collision. CONSTITUTION: A underwater measuring device comprises a GPS unit(100), a buoyancy member(200), a pressure tank(300), several state metering units(400), and a distance metering unit(500). The GPS unit generates location information by specially fixing a present location. The buoyancy member equipped in the lower part of the GPS unit has inner space and varies buoyancy by changing an inner volume by increasing and decreasing air. The pressure tank equipped at the lower part of buoyancy material provides buoyancy with an atmospheric difference. Several state metering units equipped at the lower part of the pressure tank comprise a flow measuring sensor which measures flux. The distance metering unit equipped in the lower part of a state metering unit measures a distance to an underwater bottom surface.
