A meter-in flow control circuit controls the fluid ___________.

In a meter-in flow control circuit, the primary function is to regulate the fluid that is entering the actuator. This type of flow control is employed to manage the speed of the actuator's movement, whether it's extending or retracting. By controlling the flow of fluid into the actuator, the speed can be adjusted more effectively, allowing for precise control of the actuator’s operation.

This is essential in pneumatic systems where maintaining a specific speed is crucial for the performance of machinery or processes. The regulation of the incoming fluid ensures that the actuator does not move too quickly, which could lead to inefficiencies or mechanical failure. Thus, the correct understanding of a meter-in flow control circuit hinges on its focus on the fluid entering the actuator.
