Abstract

PROCESO DE LOCALIZACION DEL NIVEL DE SEPARACION O INTERFASE, DE POSICION DESCONOCIDA, ENTRE UN LIQUIDO Y OTRO FLUIDO, LIQUIDO O GAS, EN EL CUAL SE PROCEDE POR EMISION HACIA LA INTERFASE, A PARTIR DE UNA SONDA SITUADA EN UN PUNTO DE REFERENCIA SITUADO EN EL LIQUIDO, DE UNA ONDA FORMADA POR ULTRASONIDOS, REFLEXION DE LA ONDA SOBRE LA INTERFASE, Y CAPTURA DE LA ONDA REFLEJADA, PREFERENTEMENTE EN EL MISMO PUNTO DE REFERENCIA, PARA DEFINIR UN TRAYECTO DE MEDIDA: SE MIDE UN TIEMPO DE MEDIDA QUE ES EL TIEMPO RECORRIDO POR LA ONDA, SE DISPONE VARIOS REFLECTORES A DIFERENTES DISTANCIA CONOCIDAS DEL PUNTO DE REFERENCIA, SE UTILIZA EL TIEMPO DEL RECORRIDO DE MEDIDA PARA SELECCIONAR UN REFLECTOR DE REFERENCIA QUE ES EL DE LOS REFLECTORES QUE ESTA MAS PROXIMA A LA INTERFASE, A UNA DISTANCIA DEL EMISOR INFERIOR A LA DE LA INTERFASE, Y SE DEDUCE LA LONGITUD DEL RECORRIDO DE MEDIDA UTILIZANDO EL TIEMPO DEL RECORRIDO DE MEDIDA Y EL TIEMPO EN QUE HAY AL MENOS DOS REFLECTORES EN EL MEDIO LIQUIDO, ENTRE LA SONDA Y LA SUPERFICIE Y QUE SE UTILIZA LA MEDIDA DE LA VELOCIDAD DEL SONIDO ENTRE LOS DOS ULTIMOS REFLECTORES PARA DETERMINAR LA TENDENCIA O EL GRADIENTE DE FORMA QUE EXTRAPOLE CON MAYOR PRECISION LA ALTURA DEL LIQUIDO POR ENCIMA DEL ULTIMO REFLECTOR.
