The Split method of the String class allows for filtering out empty
entries, but only when passed an array of Char or String:

Function FilteredSplit(Text As String, Sep As Char) As String()

Return Text.Split(New Char() {Sep}, _
StringSplitOptions.RemoveEmptyEntries)

End Function

> Private Function FindMeter(ByVal txt As String) As MeterAccountName
> Dim TempTxt(3) As String

'Hmmm, wouldn't it be InStrRev(Text, ":") + 1 ?
TempTxt = FilteredSplit(Right(Text, InStr(Text, ":") - 1), " "c)

What do you mean by removing the array? Keep in mind that .NET is a
garbage collected environment. You don't explicitly delete objects,
the garbage collector does that for you eventually.
