A sealed turbulent flow path Pressure Compensating dripper incorporating a diaphragm that maintains a uniform flow rate over a wide range of operating pressures.
What is Pressure Compensation?
Drip systems apply water to plants at very low rates. This minimises evaporation losses and limits the water to the root zone of the plant by putting water where it counts.
Pressure Compensating, or PC, is a term used to describe an emitter that maintains the same output at vary water inlet pressures. Therefore PC drippers compensate for an uneven terrain, length of supply tube and vary inlet flows. PC drippers facilitate controlled watering, as each dripper performs to a pre-set flow rate (eg 4 liters per hour), allowing water emitted over a length of time to be easily calculated. This ensures more efficient watering, reducing the risk of over or under watering.
A non-compensating dripper will have varying output flow at varying inlet pressures. Therefore the flow will vary along uneven terrain, and each dripper will emit a different amount of water depending on its location on the supply line. The pressure to a drip emitter can vary due to the scope of the land and the length of the supply tube. If an irrigation system is installed down a slope, there will be higher water pressure at the bottom of the slope than the top, and non compensating drippers at the bottom will emit more water than the emitters higher up on the slope. PC drippers will emit even amounts of water all the way down the slope.
