You will want to compare the ID in the messages to the ID/Barcode on your meter. It depends on the meter type, but the ID should be listed somewhere, and then you can filter out messages based on that.

You could also compare your Type field with the list here. Looks like the Type: 13 indicates a possible water meter. Hope this helps!
