Patent number: 11292710Abstract: A fluid management system includes a fluid management controller and a fluid dispenser. The controller authorizes control of the one or more fluid management components over a wireless interface. A dispensing meter can be activated by an authentication device. The fluid meter includes a cartridge valve with a valve cartridge and a valve stem. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.Type: GrantFiled: October 11, 2019Date of Patent: April 5, 2022Assignee: Graco Minnesota Inc.Inventors: Benjamin J. Paar, Bradley G. Kahler, Chad G. Igo, Gregory D. Sieckert, Mark L. Bauck, James R. Ebben, David J. Lorden, Michael E. Bloom, Shane A. Norman, Anthony J. Kuschel, Glenn E. Highland

Patent number: 11015497Abstract: The lubricant level within a reservoir is difficult to monitor, leading to the reservoir being refilled more often than necessary to ensure that the reservoir always contains lubricant. A lubricant level sensing system is connected to and monitors various aspects of the pump assembly that draws lubricant from the reservoir. The pump assembly displaces a known volume of lubricant with each pump stroke. A lubricant-level estimator calculates an estimated lubricant level remaining in the reservoir based on a stroke-count value as sensed from the pump assembly and on a reference value stored in a memory. The estimated lubricant level provides the lubricant remaining and the rate of usage such that maintenance can be scheduled ahead of time to prevent the reservoir running dry.Type: GrantFiled: January 18, 2017Date of Patent: May 25, 2021Assignee: Graco Minnesota Inc.Inventors: Brandon T. Gustafson, Suresha Saragur Nijaguna, Chad G. Igo

Patent number: 10843213Abstract: A fluid management system includes an authentication device and a fluid dispensing meter, and the fluid dispensing meter includes a processor and a memory. The authentication device is configured to provide data to the processor. The processor is configured to recall information from the memory, to compare the information to the data received from the authenticator, and to control a trigger control mechanism between the activated state and the deactivated state based on the comparison.Type: GrantFiled: October 10, 2018Date of Patent: November 24, 2020Assignee: Graco Minnesota Inc.Inventors: Bradley G. Kahler, Mark L. Bauck, Joshua R. Holmstadt, Glenn E. Highland, Benjamin J. Paar, Chad G. Igo

Patent number: 10647566Abstract: A fluid management system includes an authentication device and a fluid dispensing meter, and the fluid dispensing meter includes a processor and a memory. The authentication device is configured to provide user-identification data to the processor. The processor is configured to recall approved user identities from the memory, to compare the approved user identities to the user-identification data received from the authenticator, and to control a trigger control mechanism between the activated state and the deactivated state based on the comparison of the user-identification data and the approved user identities.Type: GrantFiled: March 22, 2018Date of Patent: May 12, 2020Assignee: Graco Minnesota Inc.Inventors: Bradley G. Kahler, Benjamin J. Paar, Glenn E. Highland, Chad G. Igo

Patent number: 10589979Abstract: A fluid management controller includes a processor, a wireless interface, and a memory. The wireless interface is configured to communicate between the processor and one or more fluid management components. The processor is configured to authorize control of the one or more fluid management components over the wireless interface. The memory is encoded with instructions that, when executed by the processor, cause the processor to provide dispense authorizations to the one or more fluid management components and record fluid dispense information from the one or more fluid management components in the memory.Type: GrantFiled: March 22, 2018Date of Patent: March 17, 2020Assignee: Graco Minnesota Inc.Inventors: Benjamin J. Paar, Bradley G. Kahler, Chad G. Igo, Gregory D. Sieckert
