A handheld computer device is configured to selectively receive a plurality of fluid output values from a paint sprayer and configured to operate in an accessible mode in which the handheld computer device is in a first location where wireless connectivity, via a continuous or near continuous communication path, to at least one of a network server or the paint sprayer is accessible or operate in an inaccessible mode in which the handheld computer device is in a second location out of range of the continuous or near continuous communication path to at least one of the network server or the paint sprayer.

Paint sprayer distributed control and output volume monitoring architectures

A plural component dispensing system includes a dispensing device, first and second fluid component sources, a system controller, and an operator interface device. The first fluid component source is connected to the dispensing device to deliver the first fluid component to the dispensing device. The second fluid component source is connected to the dispensing device to deliver the second fluid component to the dispensing device. The system controller is connected to regulate operation of the first fluid component source and the second fluid component source to produce a target ratio of the first fluid component and the second fluid component at the dispensing device. The operator interface device is remote from and operatively connected to the system controller. The operator interface device is configured to output system state information received from the system controller and to receive operator input to control an operational state of the system controller.

Operator interface device and distributed control for fluid dispensing systems

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 fluid pump control that allows for both flow control and pressure control to allow greater flexibility in applying architectural coatings.

Dual mode pump control

Sensors (and) and an interactive display () are added to an airless gas powered line striping machine () to provide the operator with a variety of information about the operating parameters. In addition to the pressure sensor/transducer () required to control the pressure through a clutch, the system includes a sensor (reed switch in the preferred embodiment) () to count pump strokes or drive revolutions, a sensor () to monitor when the gun trigger is activated and a sensor () to monitor wheel rotation (hall effect sensor detecting pulses from gear mounted on wheel in the preferred embodiment). A digital display () is included to read out measured and calculated values.
