Abstract

UN MONITOR DE NIVEL DE FLUIDO (110) PARA CONTROLAR EL NIVEL DE FLUIDO (56) EN UN DEPOSITO (50) COMPRENDE UN PRIMER PAR DE TRANSDUCTORES (66, 70) DISPUESTOS EN UN PLANO HORIZONTAL EN LA PARTE SUPERIOR Y UN SEGUNDO PAR DE TRANSDUCTORES (68, 70) DISPUESTOS EN UN PLANO HORIZONTAL EN LA PARTE INFERIOR. LOS GENERADORES DE IMPULSOS (62, 64) ENVIAN IMPULSOS ELECTRICOS A LOS TRANSDUCTORES TRANSMISORES (66, 68) QUE TRANSMITEN ONDAS DE PRESION A LA PARED DEL DEPOSITO (50). LAS ONDAS DE PRESION QUE SE PROPAGAN PERIFERICAMENTE SE DETECTAN POR MEDIO DE LOS TRANSDUCTORES RECEPTORES (70, 72) Y LOS PROCESADORES (78, 80) ANALIZAN LA AMPLITUD DE LAS ONDAS DE PRESION DETECTADAS PARA DETERMINAR SI EL FLUIDO ESTA PRESENTE O AUSENTE EN LOS PLANOS HORIZONTALES SUPERIOR E INFERIOR. LOS GENERADORES DE IMPULSOS (62, 64) SE COLOCAN PARA ENVIAR IMPULSOS FUERA DE FASE DE FORMA QUE LAS ONDAS DE PRESION QUE SE PROPAGAN AXIALMENTE PUEDAN DETECTARSE PARA DETERMINAR LAS ALTERACIONES DEL NIVEL DE FLUIDO (56) ENTRE LOS PLANOSHORIZONTALES SUPERIOR E INFERIOR. LOS PROCESADORES (78, 80) PUEDEN DISPONERSE PARA ACCIONAR ALARMAS (82, 84) O PARA ACCIONAR VALVULAS (102, 104) PARA CONTROLAR EL NIVEL DE FLUIDO (56) EN EL DEPOSITO (50).
