Hydraulic Meter In Flow Control

Supply pressure. Po, is pre-set by adjusting the pressure relief valve. Load pressure, p, is a function of the external load, F, acting on the actuator: P = F/A. Velocity, v,  is controlled by throttling the inlet flow Q = pA to the cylinder. The outlet flow from the actuator is fed straight back to tank. The salient features of the above configuration can be summarized as follows:

(1) Energy wasted by the throttling action results in lower efficiency than hydrostatic transmission, but better efficiency than meter-in /meter-out circuit.
(2) Only opposing loads can be controlled.

Meter-in flow control.
