然而，用容积法装置校准流量仪表较费时间，用此法作出厂校准感到效率低，成本高，而标准表比较法虽然效率高，但度较低，于是人们将两种方法结合起来，提出标准流量计和容积法流量标准装置结合的方法，在上文所述各类流量标准装置上。 直至某页时间大于机的的起始时间，将该页指针减1作为起始页，③需要指出的是，采样记录中设置本页存储结束标志，页内后一条记录该标志置位，查询时对读出记录的该标志进行判断，如已到后一条记录则自动转到下个存储页查询。衡水市***韩国Autovalve阀门RS80-1.5S RS80-1.5S-S-L RS80-1.5S-S-L-R RS90-2S RS90-2S-S-L RS90-2S-S-L-R零售价格
