Abstract

UN SISTEMA DE MEDICION COMPRENDE UN ALOJAMIENTO 10 CON UN CONDUCTO 11 QUE TIENE UNA ENTRADA 13 Y UNA SALIDA 14. EL FLUIDO PASA A TRAVES DE UN NUMERO DE ABERTURAS 47 EN UNA CAMARA 21 Y A CONTINUACION A TRAVES DE UN TUBO DE MEDICION 40 QUE INCORPORA EXTENSIONES 41. EL FLUIDO SALE POR LA CAMARA 22 Y SUS ABERTURAS 47 A SALIDA 14. LOS TRANSDUCTORES 6, 37 ESTAN DISPUESTOS EN LAS CAMARAS 53,50 Y TIENEN UNA TRAYECTORIA ACUSTICA A TRAVES DEL TUBO DE MEDICION. LOS DISPOSITIVOS ELECTRONICOS DE CONTROL HACEN QUE LOS TRANSDUCTORES ENVIEN UN ESTALLIDO DE SEÑALES EN DIRECCIONES ALTERNAS A TRAVES DEL TUBO PARA DETERMINAR LA VELOCIDAD DE FLUIDO.
