Performance
Hydro-Brake® Flow Control out-performs conventional flow
control devices. Its unique S-shaped head/discharge curve, which
has been devised from extensive systematic modelling and field
testing, comprises two distinct phases. As the head increases,
a transition takes place from free flow (lower portion of the
curve) to vortex controlled flow (upper portion of the curve).
The Hydro-Brake® Flow Control thereby achieves maximum
design discharge rates at lower heads than conventional controls.
As a result, storage requirements are reduced by up to 30%,
(as shown above) significantly reducing project costs.
