PURPOSE: A water level measuring instrument using a load cell is provided to facilitate the measurement of minute change of water level, since the water level is measured according to the pressure of fluid using a load cell. CONSTITUTION: A water level measuring instrument using a load cell comprises a body(100), a load cell(200), a diaphragm(300), a connection pipe(400), and a waterproof connector(500). The body is hollow. The load cell comprises a load cell holder(210), a load cell(220), and a pressure medium. The load cell holder is inserted into the body. The load cell is fixed to one end of the load cell holder and comprises a signal wire(222). The pressure medium is accepted into the other end of the load cell holder and transmits pressure to the load cell. The diaphragm is fixed to the lower part of the body to contact the load cell holder of the load cell. The pipe is formed on the lower part of the diaphragm. The connection pipe is connected to the body, and the signal wire of the load cell is embedded thereinside. The waterproof connector covers the upper end of the connection pipe.
