I built a simple Hartford loop like this guy: http://www.homebrewtalk.com/f51/my-super-efficient-5-gallon-mash-lauter-tun-92724/index3.html#post1011236. It is just a copper tee with extensions. Wort goes through silicone tubing, in the bottom, and out the side. It was easy to make and very effective. Just raise and lower the side where the wort goes out to adjust the mash tun water level
More to your question, that looks about identical to me.
