Patent number: 11703363Abstract: Embodiments described herein relate to a flow meter assembly. The inline flow meter assembly includes a housing, an elongated flow member, and a piston. The housing includes a fluid passage. The elongated flow member has a shaft portion and an opposite fluid flow portion. The fluid flow portion has an outer peripheral surface. The shaft portion is coupled to the housing. The piston has a plate. The plate has a plate orifice. The piston and the plate move axially between a no flow position where the outer peripheral surface of the fluid flow portion is engaged with the plate orifice to prevent a fluid flow and a full flow position where the outer peripheral surface of the fluid flow portion is disengaged with the plate orifice such that the fluid flow enters the plate orifice and passes through the fluid passage in the axial direction of movement of the piston.Type: GrantFiled: January 28, 2020Date of Patent: July 18, 2023Assignee: DWYER INSTRUMENTS, LLCInventors: Lars O. Rosaen, Peter E. Hackett

Patent number: 11555638Abstract: Embodiments described herein are generally directed to a venturi valve. The venture valve includes an inlet; an outlet opposite of the inlet; a passage, a primary orifice, and an insert. The passage is positioned between the inlet and the outlet and fluidly coupling the inlet to the outlet. The primary orifice is positioned between the inlet and the outlet and in fluid communication with the passage such that the primary orifice permits fluid to enter the passage. The insert is positioned between the inlet and the outlet, the insert configured to enclose at least a portion of the passage.Type: GrantFiled: March 26, 2020Date of Patent: January 17, 2023Assignee: DWYER INSTRUMENTS, LLCInventors: Lars O. Rosaen, Peter E. Hackett

Patent number: 11175086Abstract: A venturi vacuum drawback assembly includes a fluid supply passage that supplies the fluid to the device, a fluid return passage that returns the fluid to the device, a shutoff valve positioned on the fluid supply passage, a bypass passage, a bypass valve positioned on the bypass passage, and a venturi valve positioned on the bypass passage downstream of the bypass valve. The bypass passage includes an inlet and an outlet. The inlet is connected to the fluid supply passage upstream of the shutoff valve, and the outlet connected to the fluid return passage. The venturi valve includes a venturi inlet, a venturi outlet, and a primary orifice positioned between the venturi inlet and the venturi outlet. The primary orifice is connected to a drawback opening on the fluid supply passage by a conduit. The drawback opening of the fluid supply passage is positioned downstream of the shutoff valve.Type: GrantFiled: March 25, 2020Date of Patent: November 16, 2021Assignee: Universal Flow Monitors, Inc.Inventors: Lars O. Rosaen, Peter E. Hackett

Patent number: 11035483Abstract: A dual orifice venturi vacuum drawback assembly includes a fluid supply passage that supplies fluid to the device, a fluid return passage that returns fluid from the device, a shutoff valve position on the fluid supply passage, a bypass passage, a bypass valve positioned on the bypass passage, and a dual orifice venturi valve. The bypass passage includes an inlet connected to the fluid supply passage upstream of the shutoff valve, and an outlet connected to the fluid return passage. The dual orifice venturi valve is positioned on the bypass passage upstream of the bypass valve. The dual orifice venturi valve includes a venturi inlet, a venturi outlet, a primary orifice, and a secondary orifice. The primary orifice is connected to a primary drawback opening on the fluid return passage. The secondary orifice is connected to a secondary drawback opening on the fluid return passage.Type: GrantFiled: February 7, 2019Date of Patent: June 15, 2021Assignee: Universal Flow Monitors, Inc.Inventors: Lars O. Rosaen, Peter E. Hackett, Wesley Fowler
