Abstract

Dispositivo para indicar cambios en la gravedad específica de un líquido, que comprende un primer y segundo flotadores adaptados para flotar sobre la superficie de dicho líquido, disponiéndose de tal manera las formas y/o densidades de tales flotadores, que las profundidades a que éstos se sumergen en el líquido uno respecto al otro cambian en respuesta a cambios en dicha gravedad específica; y medios para producir una señal eléctrica que dependa de las profundidades a que se sumergen aquellos flotadores uno respecto al otro.
