Abstract
In one aspect, a system for regulating the flow of fluid supplied to actuators of an agricultural implement may include a tool and a fluid-driven actuator configured to actuate the tool relative to a surface. The system may also include a pump configured to supply fluid to the fluid-driven actuator and a valve configured to control a flow of the fluid supplied to the fluid-driven actuator. Furthermore, the system may include a first sensor configured to detect a parameter indicative of a first pressure upstream of the valve and a second sensor configured to detect a parameter indicative of a second pressure downstream of the valve. Additionally, the system may include a controller communicatively coupled to the first and second sensors, with the controller configured to determine a pressure differential across the valve based on measurement signals received from the first and second sensors.
