Abstract

"APARELHO PARA MEDIR PELO MENOS UM PARâMETRO DE OPERAçãO DE UM REGULADOR DE PRESSãO E OBTER DADOS DE DIAGNóSTICO BASEADO NOS PARâMETROS DE OPERAçãO, E, MéTODO PARA A REALIZAçãO DE DIAGNóSTICO EM UM REGULADOR DE PRESSãO POSICIONADO EM UMA PASSAGEM DE FLUXO DE FLUIDO". Aparelho para a realização de diagnósticos através de um regulador é descrito. O regulador de pressão é disposto em uma passagem de fluxo de fluido e possui um elemento de aceleração (32) móvel na passagem de fluxo. Uma haste (30) é fixada ao elemento de aceleração. O aparelho inclui um primeiro sensor de pressão (34) para medir a pressao a montante do elemento de aceleração, um segundo sensor de pressão (35) para medir a pressão a jusante do elemento de aceleração, e um sensor de percurso (44) para detectar a posição do elemento de aceleração. Um processador é fomecido que inclui um algoritmo armazenado para determinar a taxa de fluxo com base nos valores de pressão e de percurso medidos, e uma rotina de alarme para gerar os alarmes lógicos com base nos parâmetros operacionais medidos.
