The same Blichmann Engineering AutoSparge you know and love...but compatible with tri clamps! A lot of homebrew equipment now comes standard with tri clamp compatible flanges so now you can use Blichmann's AutoSparge without any additional adapters. 

From Blichmann's Website:

Have you longed for a sparging system with a "set-it-and-forget-it" design? The elegantly simple construction of Blichmann Engineering's AutoSparge™ automatically sets the hot liquor flow rate and liquid level in your mash tun. As you change the sparge rate into your boil kettle, the AutoSparge™ automatically responds by increasing or decreasing hot liquor flow to compensate and keeps a constant level in your mash tun.

Newly redesigned - 100% stainless steel

The AutoSparge™ level and flow control system is an awesome accessory for RIMS systems, and it also works great with gravity systems or with pumps! Wort gently rotates on top of the grain bed to reduce channeling and oxygen pick-up, and to increase extraction efficiency. With a constant hot liquor level over your grain bed, complicated rotating sparge arms are unnecessary!
