A solenoid valve in a manifold is commanded to move to a closed position. Upon activating a pump to supply fluid to the manifold via a supply line, a first pressure is determined in the supply line after commanding the solenoid valve to move to the closed position. Upon deactivating the pump to stop supplying fluid to the manifold, a second pressure is determined in the supply line. Based on a difference between the first pressure and the second pressure, the solenoid valve is determined to be one of (a) at least partially open or (b) in the closed position.

An automated mobile sprayer (AMS) includes a mobile base, an applicator arm supported by the mobile base, and a nozzle extending from the applicator arm. The nozzle receives fluid from a fluid supply and generates an atomized fluid spray for application to a surface. The applicator arm moves vertically relative to the mobile base and the surface to cause the nozzle to generate a vertical fluid stripe. The mobile base moves laterally relative to the surface to cause the nozzle to generate a horizontal fluid stripe.

A distributed pump system is disclosed. The distributed pump system comprises a supply source and a support structure arranged on or proximate an agricultural vehicle. At least two fluid distribution elements are mounted to the support structure and are coupled at an inlet to a first conduit to provide fluid communication between the fluid distribution elements and the supply source. An application system including at least two application units is coupled to one or more of the fluid distribution elements by a second conduit. A first monitoring device is associated with a respective application unit and fluid distribution element, and is configured to sense a downstream flow parameter of the second conduit and generate a corresponding output signal. An electronic control unit is communicatively coupled to each of the fluid distribution elements and is configured to dynamically adjust an input parameter of one or more of the fluid distribution elements.

A sprayer for spraying fluid includes a pump, a motor that drives the pump, a drive cycle indicator, a wireless module configured to send and receive information, and control circuitry. The drive cycle indicator outputs an indication of cycle status of the pump. The control circuitry is configured to receive the plurality of cycle status indications of the pump, determine a plurality of output values representing paint spray fluid output volume over a plurality of time windows based on the plurality of cycle status indications of the pump, store the plurality of output values in memory, and cause the wireless module to transmit one or more of the stored plurality of output values externally from the sprayer.

A sprayer control system includes a plurality of smart nozzles each having at least one control valve with a valve operator, an electronic control unit for the valve operator, and one or more spray nozzles. The at least one control valve and the ECU control a flow rate of liquid agricultural product through the nozzles. A duty cycle modulator is in communication with the ECU and generates an applied duty cycle for the at least one control valve. The duty cycle modulator includes a specified duty cycle input having a specified duty cycle and a pressure monitor associated with the at least one control valve. A pressure comparator compares the valve pressure determined with the pressure monitor with a system pressure and generates a pressure error. An applied duty cycle generator generates the applied duty cycle based on the specified duty cycle modified by the pressure error.

A dispensing system for dispensing a fluid, the fluid being water or a water-based mixture, includes a dispensing unit and a cleaning unit. The dispensing unit includes a connection unit for connecting the dispensing unit to a supply of the fluid, a dispensing head for dispensing the fluid, and a flexible hose for guiding the fluid from the connection unit to the dispensing head. The cleaning unit includes a cleaning attachment unit for attaching the cleaning unit to the connection unit, a cleaning fluid delivery unit configured to deliver cleaning fluid to the dispensing unit via the cleaning attachment unit, and a receptacle unit configured to accommodate the dispensing head and to receive fluids exiting the dispensing head.
