Abstract
PROCEDIMIENTO PARA LA MEDIDA MAGNETICO-INDUCTIVA DEL CAUDAL Y CAUDALIMETRO MAGNETICO-INDUCTIVO CORRESPONDIENTE. SEGUN EL PROCEDIMIENTO, UNA MAGNITUD DE MEDICION GENERADA MEDIANTE UN CAMPO MAGNETICO PERIODICAMENTE ALTERNATIVO, CONSTANTE POR SECCIONES, ES ELABORADA EN UNA SECCION DE CADA SEMIPERIODO. SE GENERA UNA MAGNITUD DE SIMULACION CONSTANTE POR SECCIONES, DE TAL MODO QUE LA MISMA VARIA SINCRONICAMENTE RESPECTO AL CAMPO MAGNETICO Y ES ELABORADA EN OTRA SECCION DE CADA SEMIPERIODO ALTERNATIVAMENTE CON LA MAGNITUD DE MEDICION, DEL MISMO MODO QUE LA MAGNITUD DE MEDICION, PARA DAR VALORES DE SALIDA. EL CAUDALIMETRO PRESENTA UN PRIMER GENERADOR (7) DE SEÑAL DE SIMULACION PARA LA GENERACION DE UNA SEÑAL DE SIMULACION, QUE ESTA UNIDO CON UNA ENTRADA DE UN CONMUTADOR (8), A CUYO EFECTO UN AMPLIFICADOR (5) ESTA UNIDO CON LA OTRA ENTRADA DEL CONMUTADOR (8) Y LA SALIDA DEL CONMUTADOR (8) ESTA UNIDA CON UN CIRCUITO DE VALORACION (9).
