GEOSystems strives to identify the most suitable Vortex Flow Control for all flow control situations.

Our devices are normally made using 10 gauge (3mm) Grade 304 stainless steel and to all the relevant British Standards, matching the specification of the perceived market leaders. Certificates of Conformity can be supplied with each unit, if required.

Stainless steel does not corrode, and is highly resistant to abrasion, so the life expectancy of each unit is likely to exceed that of the system into which it is installed.

Following installation there is little need for maintenance. Units come equipped with a drain down/bypass mechanism which is remotely operated from ground level.

In the unlikely event of a blockage occurring in the inlet or outlet of the Vortex Flow Control, the mechanism allows drain down of the system without the need for expensive over pumping or bypass penstocks and pipe work. This is unlike other makes of Vortex Flow Controls, which can only bypass a blockage in the inlet.

GEOSystems Vortex Flow Controls

The GEOSystems vortex flow control (VFC) is a self-activating flow control device which induces a vortex motion in the flow to control the rate at which water is allowed to enter downstream drainage systems. The energy inherent in the water flow is harnessed to generate the vortex and hence has no need of external energy requirements. The flow control itself has no moving parts.

The VFC has a superior hydraulic performance when compared to conventional flow controls such as orifice plates, throttle pipes and penstocks. With outlet diameters up to 400% larger than conventional flow control devices, the risk of blockage is minimised.

VFCs have a unique head/flow characteristic with a distinctive 'S' shaped curve with high flush and kick-back flow points.This characteristic can reduce storage volume requirements, thereby lowering project costs.
