Abstract
EL MEDIDOR DEL FLUJO DE UN FLUIDO COMPRENDE UNA PAREJA DE TRANSDUCTORES (8, 9) SEPARADOS EN LA DIRECCION DEL FLUJO DE FLUIDO. UN TRANSMISOR (20) HACE QUE SE TRANSMITAN SEÑALES ACUSTICAS EN AMBAS DIRECCIONES A TRAVES DEL FLUIDO MEDIANTE LOS TRANSDUCTORES. UN PROCESADOR (22) DETERMINA LA INFORMACION RELATIVA AL FLUJO DEL FLUIDO MEDIANTE LA SUPERVISION DEL TIEMPO DE TRANSMISION DE LAS SEÑALES ACUSTICAS RECIBIDAS POR LOS TRANSDUCTORES. PARTE DEL ESPACIO ENTRE LOS TRANSDUCTORES DEFINE UN CONDUCTO PARA EL FLUJO, QUE CONSISTE EN UNA ESTRUCTURA DE FLUJO (5) QUE TIENE UNA PLURALIDAD DE PASAJES DE FLUJO DE FLUIDO PARALELOS (51,52; 61, 62; 71, 72) QUE SE EXTIENDEN AXIALMENTE EN LA DIRECCION DEL FLUJO, DONDE LOS DIAMETROS DE LA SECCION TRANSVERSAL DE LOS PASAJES ESTAN ELEGIDOS DE TAL FORMA QUE ONDAS ACUSTICAS SUSTANCIALMENTE PLANAS SOLO SON TRANSMITIDAS A TRAVES DE LOS PASAJES MEDIANTE EL FLUIDO, Y DONDE BAJO CONDICIONES DE FUNCIONAMIENTO EL FLUJO FLUYE A TRAVES DE CADA PASAJE, DE TAL MODO QUE LA RELACION ENTRE EL COEFICIENTE DE FLUJO A TRAVES DEL PASAJE EN RELACION CON EL COEFICIENTE DEL FLUJO DEL VOLUMEN TOTAL PERMANECE SUSTANCIALMENTE CONSTANTE CON RESPECTO AL COEFICIENTE DE FLUJO DEL VOLUMEN TOTAL.
