Abstract
CAUDALIMETRO VOLUMETRICO DEL TIPO QUE UTILIZA LA FORMACION DE UN VORTICE. COMPRENDE UNA CAMARA (11) CON SIMETRIA DE REVOLUCION ALREDEDOR DE UN EJE PROVISTA EN SU PERIFERIA DE UNA HENDIDURA DE INTECCION (12), Y EN SU CENTRO, DE MEDIOS DE ESCAPE AXIAL DE FLUIDOS (18). DE UN DETECTOR DE VELOCIDAD, CONSTITUIDO POR DOS TERMOELEMENTOS, EMISOR (22) Y RECEPTOR (23), DESPLAZADOS ESTOS ANGULARMENTE ALREDEDOR DEL EJE SITUDADOS EN LA ZONA DONDE LA VELOCIDAD CIRCUNFERENCIAL DEL VORTICE ES PROPORCIONAL AL CAUDAL. UN CIRCUITO DE MEDICION DEL INTERVALO DE TIEMPO ENTRE LA APLICACION DE LOS IMPULSOS ELECTRICOS Y LA DETECCION POR EL TERMOELEMENTO RECEPTOR (23), EN EL QUE LOS IMPULSOS SERAN APLICADOS CON FRECUENCIA CONSTANTE. SE APLICA UN IMPULSO ELECTRICO DE CALENTAMIENTO EN RESPUESTA A LA DETECCION, SIENDO LA FRECUENCIA DE IMPULSOS PROPORCIONAL A LA VELOCIDAD DE ROTACION Y, POR TANTO, AL CAUDAL. DE APLICACION EN LA MEDICION DEL CONSUMO DE COMBUSTIBLE PARA MOTOR DE COMBUSTION INTERNA. P
