Abstract
UN MEDIDOR DE VELOCIDAD DE CAUDAL POR ULTRASONIDO SEGUN EL PROCEDIMIENTO DE DIFERENCIA DE FASES, MEDIANTE UN TRAYECTO DE MEDICION DE CAUDAL CON DOS TRANSPORTADORES DE ULTRASONIDO (W1,W2) COLOCADOS ENFRENTE EN EL EJE DEL CAUDAL. LOS TRANSPORTADORES DE ULTRASONIDOS (W1,W2) SE ACCIONAN RITMICAMENTE UN OSCILADOR (OSZ) Y CON AMPLIFICADORES DE RECEPCION (V1,V2) INDIVIDUALMENTE DISPUESTOS PARA LOS TRANSFORMADORES DE ULTRASONIDOS (W1, W2) CON DISPOSITIVOS DE VALORACION. DURANTE LA RECEPCION DE LA SEÑAL DE ULTRASONIDOS SE VALORA LAS SEÑALES QUE SE RECIBEN EN LAS SALIDAS DEL AMPLIFICADOR DE RECEPCION (V1,V2). CUALQUIER AMPLIFICADOR DE RECEPCION (V1,V2) ESTA UNIDO DE FORMA FIJA AL TRANSFORMADOR DE ULTRASONIDOS (W1,W2) TAMBIEN SE VALORAN DURANTE EL ENVIO DE SEÑALES DE ULTRASONIDOS Y LA DIFERENCIA DE FASES SE UTILIZA COMO TAMAÑO DE REFERENCIA, A LA CUAL SE REFIERE LA DIFERENCIA DE FASES DURANTE LA RECEPCION.
