„Meter in” is a flow control method use with an application of 2 and 3 -way flow control valves.

A metered flow – to be easy to remind – adjust a flow of fluid at a controlled rate.
I will discuss about “meter in” method
Flow control in a hydraulic system is achieve by a flow control valve. Flow control valves are use to keep a set flow constant regardless of pressure variations.
“Meter in” circuit is use to control the extension stroke speed of an actuator, a hydraulic cylinder that is either push or lift a load.
This type of control is recommended for hydraulic system in which the actuator, hydraulic cylinder, acts against a positive resistance – opposing force – to the controlled flow
For example when a load is lift or push, where the load pressures have a continuous positive value. Positive value of pressure is the actuator act against a positive resistance to the controlled flow.
Slip-stick effect
If meter in control is used, so-called slip-stick effect is possible to occur. This effect is more often encountered in the field of pneumatics, but also run into in the hydraulics field. Because oil, unlike air is not readily compressible, the jerky outward motion of the hydraulic actuator – cylinder- that occurs will hardly be noticed. This may be observed as a vibrating inward and outward movement of the cylinder that is sometimes even audible.
