If "erb.txt" is

<2.54   3.11   2.89>
<3.58   5.24   5.66>

Then this file can be read using

inpf = OpenRead["erb.txt"];
idat = ReadList[inpf, Record]
Close[inpf]

pdat = StringReplace[#, {"<"->"", ">"->""}]& /@ idat
fdat = ReadList[StringToStream[#], Number]& /@ pdat 

If you like, replace the first three lines above with Import["Erb.txt",
"Table"];

Regards,

Dave.
