What device is used to adjust water flow pressure in fertilizer application?

The device used to adjust water flow pressure in fertilizer application is a pressure regulator. This type of device is crucial for ensuring that the pressure of the water remains constant, regardless of changes in the supply line pressure or variations in demand. In fertilizer application, maintaining the correct pressure is vital for achieving uniform distribution of the fertilizer solution across the target area.

Pressure regulators function by reducing the high pressure from a source, such as a municipal water line or a storage tank, to a lower, stable pressure needed for effective application. This helps protect the irrigation system and ensures efficient delivery of nutrients to plants. By utilizing a pressure regulator, applicators can optimize their systems for both effectiveness and efficiency, avoiding issues related to over or under-application of fertilizers.

In contrast, other devices such as water meters focus on measuring the volume of water used, flow regulators manage the flow rate rather than pressure, and output adjusters are typically used for controlling how much output is delivered rather than the pressure itself.
