Abstract: The mechanism that we propose is a water level sensor (Tide-Gauge), using the Archimedes principle, according to which a body immersed in a fluid in equilibrium, subjected to on behalf of this one a thrust which the intensity is equal to the weight of the fluid displaced. It is composed of an electromagnetic sensor forces of which is suspended a plunger cylindrical glass. The latter is partially introduced into a measuring cylinder filled with water. The electromagnetic sensor of forces allows us to measure the difference between the weight of the cylinder and the force due to the buoyancy exerted by the water on the submerged part of the cylinder. When the water level in the test piece changes it is implied by a variation of the submerged portion of the cylinder, and causes a variation of the buoyancy, as a consequence of variation of the force exerted on the sensor. The electromagnetic sensor allows the conversion of this force into a voltage by the intermediate of an electronic circuit

Keywords: Electromagnetic Sensor of Force, Water Level Detector, Tide-Gauge.
