Abstract

UN MEDIDOR DEL FLUJO DE UN FLUIDO COMPRENDE UN PAR DE TRANSDUCTORES (1, 2) SEPARADOS EN LA DIRECCION DEL FLUJO DE FLUIDO. UN TRANSMISOR (13) ESTA CONECTADO MEDIANTE UN PRIMER CIRCUITO ELECTRICO A LOS TRANSDUCTORES (1, 2) PARA PROVOCAR QUE LAS SEÑALES ACUSTICAS SEAN TRANSMITIDAS EN AMBAS DIRECCIONES A TRAVES DEL FLUIDO MEDIANTE LOS TRANSDUCTORES. UN PROCESADOR (13) SE CONECTA A LOS TRANSDUCTORES (1, 2) MEDIANTE UN SEGUNDO CIRCUITO ELECTRICO PARA DETERMINAR LA INFORMACION RELATIVA AL FLUJO DEL FLUIDO MONITORIZANDO EL TIEMPO DE VUELO DE LAS SEÑALES ACUSTICAS RECIBIDAS POR LOS TRANSDUCTORES. EL PROCESADOR (13) ESTA DISPUESTO PARA MONITORIZAR EL TIEMPO DE VUELO DE LAS SEÑALES ACUSTICAS TRANSMITIDAS ENTRE LOS TRANSDUCTORES A LO LARGO DE UN PRIMER Y UN SEGUNDO CAMINO ACUSTICO DIFERENTE DEL PRIMERO QUE PASAN A TRAVES DEL FLUIDO.
