Far more efficient than using external tools such is sed is bash's built-in parameter expansion support. For instance, if you want the name variable to contain everything until the first number, and the numbers variable to contain everything after the last alpha character:

version=METER1.2.1
name=${version%%[0-9]*}
numbers=${version##*[[:alpha:]]}

To understand this, see the BashFAQ entry on string manipulation in general, or the BashFAQ entry on parameter expansion in particular.
