What is a meter-in flow control configuration?

A meter-in flow control configuration refers to a setup where a flow control valve is located downstream of the pump and upstream of the actuator. This arrangement is important because it allows for the regulation of flow into the actuator, which controls the speed at which the actuator moves or the force it generates.

In this configuration, the flow control valve modulates the fluid's flow rate entering the actuator based on the desired performance. By adjusting the valve, the operator can change the amount of fluid delivered to the actuator, effectively controlling its action. This setup is particularly useful in applications where precise control of speed or position is required, as the actuator receives a steady supply of fluid while the flow volume is regulated.

This understanding clarifies that in a meter-in configuration, the goal is to manage the flow rate before it reaches the actuator, enabling smooth operation and responsiveness to control signals.
