What exactly are you referring to as "Series 1", etc?
There were* Flash Comics (1940-1949), an anthology comic book where the original Flash (Jay) was just one of several features.
* All-Flash (1941-1947/48) which was the Golden Age Flash's solo-title
* The Flash (1959-1985) which starred Barry as the Flash
* Flash (1987-2006) featuring Wally taking over the role of Flash
* Flash: The Fastest Man Alive (2006-2007) when Bart was Flash
* The Flash (2007-2009) which was a return to Wally as Flash and continued the numbering from his previous run
* The Flash: Rebirth (2009-2010) a six-issue series that brought back Barry as the Flash
* The Flash (2010-2011) which was Barry as the Flash
* The Flash (2011-2016) Barry's New 52 series
and currently
* The Flash (2016-present) Barry's series under Rebirth
Not to mention other specials and annuals, not to mention Barry's occasional features in other comic books like Showcase and Adventure Comics.
