What does the agitator do in a spray system?

In a spray system, the primary role of the agitator is to maintain uniformity and consistency of the formulated product by preventing it from settling. From a practical standpoint, when various components in a liquid formulation are allowed to sit without agitation, heavier particles may settle at the bottom of the tank, leading to an uneven application and inconsistency when the spray system is in operation. By keeping the product mixed and suspended, the agitator ensures that the ingredients remain homogenous, enabling effective spraying without interruptions or variations in delivery.

The other options, while relating to the operation of a spray system, do not accurately describe the specific function of the agitator. The generation of system flow typically involves pumps or other mechanical components rather than the agitator itself. Measuring pressure is the role of specialized sensors close to the nozzle, and while nozzle issues can occur, clog prevention is generally achieved through filtration and proper system design rather than agitation. Thus, maintaining product suspension is the crucial task that the agitator performs in a spray system, making this option the correct one.
