Abstract

SE PRESENTAN UNA TECNICA Y UN SISTEMA NO INVASIVOS PARA MEDIR EL FLUJO DE UN LIQUIDO DIRIGIDO POR UN DIAFRAGMA FLEXIBLE DE UNA BOMBA DE MEMBRANA (18). SE CONTROLAN DE FORMA CONTINUA EL FLUJO, PRESION Y/O TEMPERATURA DE UN GAS, TAL COMO AIRE, UTILIZADO PARA ACCIONAR LA BOMBA (18). SE PUEDE CALCULAR EL VOLUMEN INSTANTANEO DE LIQUIDO QUE ENTRA O SALE DE LA CAMARA DE LA BOMBA (18) A PARTIR DE LOS VALORES MEDIDOS DEL GAS UTILIZADO PARA ACCIONAR LA BOMBA (18). SE UTILIZAN UNOS DETECTORES (10, 12 Y/O 14) PARA MEDIR LOS VALORES RELATIVOS AL GAS. LOS PARAMETROS DETECTADOS SE CONTROLAN DE MANERA CONCURRENTE Y CONTINUA PARA DETERMINAR LA CANTIDAD DE GAS QUE ENTRA Y SALE DEL DIAFRAGMA DE LA BOMBA DE MEMBRANA (18) UTILIZADA PARA MOVER EL LIQUIDO POR DENTRO DE UN CONDUCTO PARA EL LIQUIDO. LAS MEDIDAS SE PUEDEN UTILIZAR ENTONCES PARA CALCULAR LA VELOCIDAD DE FLUJO INSTANTANEA DEL LIQUIDO.
