A close up view of stainless steel flow tranquilizer racks mounted in the approach section of a fiberglass 1.5-foot H flume.

Tranquilizer racks help to dampen excess flow stream energy, dampen surface turbulence, and straight out the velocity profile prior to the flow stream entering the flume itself.  The drop-in-place nature of the racks means that they can be used to correct flows for both new and existing flume installations.
