Full Product Manual

distribution tubing See 1/4" distribution tubing.
drip emitter a low-volume emission device that delivers water at low flow rates, one drip at a time;
drip emitters are used to apply water directly to an individual plant root zone.
emission device a low-volume irrigation component that delivers water directly to the plants; emission
devices can include bubblers, drip emitters, microsprays and inline emitter tubing.
filter a device used in a control zone or multi-outlet emission device to screen dirt and debris
from the water; filters are important in low-volume systems because the small emission
devices can easily become clogged.
flow the amount of water, usually measured in gallons per minute or gallons per hour, that ca
n
pass through an irrigation system.
GPH an abbreviation for gallons per hour, which is a measure of the flow of water through a
n
irrigation system; GPH is typically used to measure flow in low-volume irrigation
systems.
GPM an abbreviation for gallons per minute, which is a measure of the flow of water through
an irrigation system; GPM is typically used to measure flow in conventional irrigation
systems.
hydrozone a grouping of plants served by one control zone and irrigated by a low-volume system; a
hydrozone typically has a common microclimate and may consist of plants with like
water requirements or with mixed water requirements.
inline emitter tubing a polyethylene tube with emitters pre-installed at a specific distance from each other
a
the factory.
infiltration rate the rate at which water applied to the soil enters the soil without causing runoff.
low-volume irrigation a type of watering system in which a precise amount of water is applied directly to the
root zones of plants, typically in gallons per hour.
matched hydrozone a hydrozone in which all of the plants have the same water needs; plants in a matched
hydrozone may each be watered by the same type and number of emitters and typically
will be watered together on the same valve.
maximum system run
time
the longest period of time a low-volume irrigation system can run without water loss to
deep percolation (or water penetration below the plant root zone).
micro-bubbler a low-volume emission device that delivers water at higher flow rates than drip emitt
e
but at lower flow rates than micro-sprays; micro-bubblers are used to apply water
directly to an individual plant root zone.
