Abstract
UN ANEMOMETRO QUE COMPRENDE UNA CAVIDAD CON RESONANCIA ACUSTICA (1) ENTRE DOS PLACAS (2 Y 3) Y ABIERTO EN LA DIRECCION DEL FLUJO DE LIQUIDO. LA CAVIDAD TIENE AL MENOS UN PAR DE TRANSDUCTORES ELECTRO-ACUSTICOS (5) QUE SON EXCITADOS A UNA FRECUENCIA PROPIA PARA PRODUCIR UNA ONDA ESTACIONARIA PERPENDICULAR A LA DIRECCION DEL FLUJO DE LIQUIDO Y UNA ONDA MOVIL PERPENDICULAR A LA ONDA ESTACIONARIA. UTILIZANDO LOS RETARDOS DE TIEMPO O LOS DESPLAZAMIENTOS DE FASE ENTRE LA SEÑAL QUE EXCITA UN TRANSDUCTOR Y LA SEÑAL GENERADA POR LA RESPUESTA DEL OTRO TRANSDUCTOR, PUEDE CALCULARSE LA VELOCIDAD DEL FLUJO DE LIQUIDO. SE SUMINISTRA UNA COMPENSACION PARA LOS CAMBIOS EN LA FRECUENCIA PROPIA PROVOCADOS POR LOS CAMBIOS EN EL ENTORNO.
