Abstract

EL MEDIDOR DEL CAUDAL DE FLUIDOS (10) INCLUYE UNA MEMBRANA FLEXIBLE (35) FORMADA DE UN MATERIAL FLEXIBLE Y CONTIENE UN APARATO PARA PROPORCIONAR ELASTICIDAD A LA MEMBRANA (35) PARA QUE SE ONDULE. LA MEMBRANA (35) SE ENCUENTRA MONTADA EN LA TRAYECTORIA DE FLUJO DEL FLUIDO DE MODO QUE PARES DE CARAS DEFINEN CON EL ALOJAMIENTO, SIMULTANEAMENTE, UNAS JUNTAS DE ESTANQUEIDAD IMPERMEABLES A LOS LIQUIDOS (67) EN AL MENOS DOS LUGARES DIFERENTES A LO LARGO DE LA TRAYECTORIA DE FLUJO. LA MEMBRANA (35) SE FLEXIONA PARA ASI PERMITIR EL PASO DE CANTIDADES DISCRETAS (62A) DE UN FLUIDO, CADA UNA CON UN VOLUMEN CONOCIDO. EL MEDIDOR DEL CAUDAL (10) GENERA UNAS SEÑALES ELECTRICAS CORRESPONDIENTES A LA FLEXION DE LA MEMBRANA (35) Y LAS SEÑALES ELECTRICAS SE CONTROLAN PARA DETERMINAR LA VELOCIDAD DE FLUJO DEL FLUIDO.
