Compare this chart (CLT ILS 36C) to the chart for CLT ILS 36L. For 36L, the missed approach is determined by DME from the localizer. Above the missed approach point, there is a "D1.3" in bold. That is DME for determining the MAP.

If it doesn't have the DME listed above, along with where you are getting that DME information from (identifier of loc or vor), then it will be determined by time for a localizer only approach.
