Due to a change in the design of this meter in September of 1989, it is necessary to determine whether your meter is of current or previous design. Standard serial numbers up to and including 6252, and special serial numbers up to and including 200995 are considered previous design. Numbers higher than those are considered current design. Should either an upstream or downstream cone require replacement on a previous design meter, it will be necessary to replace both at the same time. Cones on current design meters can be replaced individually.
