A method and system for maintaining desired water levels in a gravity flow fountain. The fountain includes manifolds that define reservoirs for storing water. The fountain is capable of generating displays by expelling variably sized and arranged water droplets, at varying rates, from the reservoirs. The expelled water must be replaced in the reservoir to continue sustained operation of the fountain. Even though the volume of water needed at each reservoir as the fountain operates is non-constant and varying, the water is controllable, and therefore, predictable. The fountain uses a programmable logic device, in combination with a variety of components, to anticipate the need for water in the reservoirs. The fountain can also use programmable logic devices, in combination with sensors and a variety of components, to historically determine the need for water in the reservoirs or meet water supply demands on a real time basis. |
