StormBrake Vortex Flow Control Device

FP McCann
PT/398/0217

Scope

To assess the FP McCann StormBrake vortex flow control system which is applicable to surface water applications with design flows from 3l/s up to 40 l/s, with a hydrostatic head of range of 0.4m to 2.0 m.

Description

The system is designed:

  • to control the rate of discharge of surface water from attenuation tanks or other storage. The flow rate is achieved by creating a vortex in the outlet once a defined head of water is reached.

  • for a given location based upon allowable discharge, pipe sizing and water level. The system is fabricated entirely from stainless steel other than the backing plate and door seals.
