POSITION-TRACKING DEVICE FOR FRESHWATER-SALTWATER INTERFACE AND A DEVICE FOR INSTALLING THEREOF

摘要

PURPOSE: An underground saline water tracking apparatus is provided to measure the level, the temperature and the electric conductivity of the underground saline water by installing buoyancy inducing member to a wireless measuring sensor and moving according to the location change of fresh water level. CONSTITUTION: An underground saline water tracking apparatus tracks the level of fresh water by installing a wireless measuring sensor into a measuring place for fresh water near coast. The tracking apparatus comprises a buoyancy inducing member of which lower part is sealed and which has a scale mark, a cap for sealing which is detachable to the upper part of the buoyancy inducing member, a form flexible metallic member which is attached to the cap and expanded to a circle line based on the diameter of the measuring place, a wireless measuring sensor equipped in the lower part of the buoyancy inducing member and a hole which surrounds the wireless measuring sensor and connected with the lower part of the buoyancy inducing member with a screw.
