Pressure for Dancing Waters

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure for Dancing Waters

Dancing waters, waltzing waters or other terms for describing the combination of colors and the motion of water in a fountain with several spouts rely on changes in and controlling the pressure for a defined time at each point in a water grid.

The computer-controlled systems consist of water, holding tanks, pumps to create pressure, solenoid operated valves, lighting and quite a few cleaver design tricks. For one of world’s most famous fountains, the one at the Bellagio in Las Vegas, uses only white lights. The number of sprayers and the height more than make up for the lack of color, especially with the majestic hotel in the background.

The fountain has over 1,200 sprayers that include 16 super jets that launch water 460 feet in finales. Called shooters by Wet Design that constructed the system, four different types of shooters are identified:

      • Programmable oarsman make the water dance up to 77 feet
      • Minishooters reach 100 feet
      • Supershooters achieve 240 feet and
      • Extreme-shooters can propel water up to 460 feet

Design aspects of each type vary but the SuperShooter has a 12-ft high holding tank, 1 foot in diameter that contains about 765 gallons. When air stored at 200 psi in 60-gallon receivers is released into the tank, the water climbs up to 240 feet. In contrast, smaller shooters with smaller tanks only require a few psi of air pressure to send water 10 to 12 ft into the air.
