There are different ways power can be metered in hydraulic systems. It is useful to distinguish between two main principles: Power‐on‐Demand and metering by energy dissipation (or valve control). As appropriate, these principles apply either to the hydraulic power source or to the hydraulic power target destination. Power‐on‐Demand metering method consists of acting on either the rotational speed or the drive torque of the pump. This principle works when the mechanical power source driving the pump can be adjusted with sufficient accuracy and dynamic. Metering by hydraulic restriction consists of inserting one or more hydraulic resistances between the hydraulic power source and each user. The transmission of information in the electrical form for hydraulic power actuators has become mainstream. The universalization of this technology was made possible by the availability and maturity of proportional and dynamic electro‐hydraulic power interfaces, that is, servovalves (electro‐hydraulic servovalve).
