Sequencing Fountain

History

The patented ChoreoSwitchâ was developed in 1998 as a means to achieve fast and smooth water sequencing effects within a large water feature. A solenoid device can produce sequencing effects of up to 10x per second at high switching speeds with no waterhammer. ChoreoSwitches were first used in Kuala Lumpur’s City Center “Lake Symphony” fountain in Malaysia.[1] KLCC[2] boasts a backdrop of The Petronas Towers, amongst the tallest buildings[3] in the world from 1998 to 2004 and still considered the tallest twin towers in the world.

How Used

Over the past number of years fountain designers have been experimenting with interactive water features enticing the viewer in to participate. Fountains that entertain and are choreographed with music and color-changing lights have become more popular. The proprietary ChoreoSwitch is a sequencing device that is used in play decks or more traditional decorative fountains.

About Switching Devices

Decorative fountain systems employ fluid amplifiers[4] to generate their decorative displays and effects. Fluid amplifiers rely on a fluid control stream to switch a fluid power stream. Fluid amplifiers are so named because a low-energy fluid control signal can control and switch a high-energy fluid power stream to produce an output signal of higher energy level than the fluid control signal. In fluid amplifiers, a fluid power stream, after leaving a nozzle, is switched selectively to one or more of a plurality of outlet passages. This may be done by supplying fluid control pressure continuously, or as a pulse, to one of the control ports at the exit end of the nozzle until the high-energy power stream is diverted. Alternatively, switching may be effected by closing the other control port so that the fluid that is flowing in through one control port from the atmosphere or some other source will create a sufficient fluid pressure imbalance adjacent the exit end of the nozzle to effect switching of the fluid power stream.

In use, a fluid amplifier would typically be connected to, and receive the high-energy power stream from, a separate fluid supply manifold that had been previously installed.
