What is the goal of pressure compensation in irrigation systems?

The goal of pressure compensation in irrigation systems is to ensure even distribution of water. When different parts of an irrigation system experience varying levels of pressure, it can lead to uneven water application. Pressure-compensating devices, often found in drip emitters or sprinkler heads, adjust the flow rate based on the pressure to provide a consistent output, regardless of fluctuations in pressure throughout the system. This capability is particularly important in systems where elevation changes, long runs of tubing, or variations in water supply can impact pressure. By maintaining an even flow rate, pressure compensation helps to optimize water usage and promotes healthier plant growth through uniform coverage.
