The speed of hydraulic actuators is controlled by managing either
the inlet flow rate, meter-in control, or the outlet flow rate, meter-out
control. The meter-in control is preferred when moving against the
load, while the meter-out control is obligatory when moving in the
same direction of the load. However, if the load direction is not determined
or reversible, the meter-out control is the best choice.
