An emitter is an element of a drip irrigation system that transfers water from the water source to the plant, tree or shrub it is intended to water. Emitters have also been referred to as drippers since they apply water to the landscaping through a slow steady drip to the landscape roots.
There are three types of emitters:
1. High Flow Emitters – intended to water larger trees and shrubs. They yield an average output of 5 gallons per hour.
2. Medium Flow Emitters – intended for plants and shrubs @ 24″ wide. They yield an average output of 2 gallons per hour.
3. Low Flow Emitters – intended for small starter plants, shrubs and flowers. They yield an average output of 1 gallon per hour.
Emitters are installed into 1/4″ – 1/2″ tubing called drip line. The tubing is punctured and the emitter is installed into the tubing with an insertion tool. Emitters come as open flow emitters, fixed flow emitters or variable flow emitters. Having emitters that regulate the volume of water applied as well as the type of water flow will help you water your roses differently then your Queen Palm.
