Abstract
UN MEDIDOR DEL CAUDAL DE UN FLUIDO COMPRENDE UN CONDUCTO (1) A TRAVES DEL CUAL EL FLUIDO FLUYE POR MEDIO DE UN MEDIO DE ENTRADA (6) Y UN MEDIO DE SALIDA (7) PARA LA MEDIDA DE LA VELOCIDAD DEL FLUJO. SE SUMINISTRA UN PRIMER TRANSDUCTOR (4) PARA TRANSMITIR SEÑALES A Y PARA RECIBIR SEÑALES DESDE UN TRANSDUCTOR SECUNDARIO (5) POR MEDIO DEL CONDUCTO (1). EL SEGUNDO TRANSDUCTOR (5) ESTA SEPARADO DEL PRIMER TRANSDUCTOR (4) A LO LARGO DEL CONDUCTO (1) PARA TRANSMITIR Y RECIBIR SEÑALES DESDE EL PRIMER TRANSDUCTOR (4). SE SUMINISTRAN MEDIOS EN FORMA DE UN DETECTOR (8) PARA DETECTAR EL TIEMPO DE VUELO DE LAS SEÑALES ENTRE LOS TRANSDUCTORES (4, 5) PARA MEDIR LA VELOCIDAD DE FLUJO DEL FLUIDO A LO LARGO DEL CONDUCTO (1). UN MEDIO EN FORMA DE UNA VARILLA (9) SE EXTIENDE A LO LARGO DEL CONDUCTO (1) PARA SUMINISTRAR UN CAMINO DE FLUJO ANULAR (10) PARA EL FLUIDO A LO LARGO DEL CUAL, DURANTE SU USO, SE TRANSMITEN LAS SEÑALES.
