Abstract
A spray nozzle for an agricultural sprayer includes a first actively controlled valve configured to control flow through the spray nozzle. A first pressure sensor is disposed upstream of the valve and a second pressure sensor is disposed downstream of the valve. The position of a valve member of the valve can be sensed, and a size of a restrictive orifice defined by the valve can be determined based on the sensed position of the valve member. A controller is configured to determine a flow rate through the valve based on a difference between a first pressure reading from the first pressure sensor and a second pressure reading from the second pressure sensor.
