Most commonly used in smaller fountain spray rings, this level independent nozzle has its jet above the surface of the water. If the water level drops, the water stream is unaffected. The water stream is typically less turbulent with this type of brass nozzles requiring less pump power. The pattern with this type of nozzle is defined by the jet orientation and not surface wave action within the pool. These nozzles are better for large interactive fountains as well as fountain applications requiring a precise stream of water such as spitting fountains. Level independent nozzles include jet, cluster, 3-tier, finger, dome and most specialty nozzles.
