Patent number: 11656236Abstract: Various embodiments include an exemplary apparatus and method for insitu calibration of multiple flow-sensing devices within a dilution system. In one example, a calibration and dilution system includes a first mass-flow device to serve as a global reference, a second mass-flow device configured to be coupled to and provide a supply of clean gas to a primary diluter, and a third mass-flow device configured to be coupled to and provide a supply of clean gas to a secondary diluter, where the diluters are pneumatically coupled to one another through a gas-supply line. Multiple valves are coupled to at least the mass-flow devices and the diluters. The calibration and dilution system is arranged so that the mass-flow controllers can be calibrated in-situ without having to remove any of the mass-flow controllers from the calibration and dilution system. Other apparatuses, designs, and methods are disclosed.Type: GrantFiled: December 31, 2019Date of Patent: May 23, 2023Assignee: TSI IncorporatedInventors: Aaron Serafin Avenido, Russell R. Graze, Jason Paul Johnson, Robert C. Anderson

Patent number: 11519841Abstract: The disclosed subject matter compensates or corrects for errors that otherwise would be present when a measurement is made on a condensation particle counting system with the only difference causing the errors being absolute pressure. The difference in absolute pressure may be due to, for example, a change in altitude in which the condensation particle counting system is located. Techniques and mechanisms are disclosed to compensate for changes in particle count, at a given particle diameter, for changes in sampled absolute pressure at which measurements are taken. Other methods and apparatuses are disclosed.Type: GrantFiled: May 28, 2019Date of Patent: December 6, 2022Assignee: TSI IncorporatedInventors: Robert Caldow, Jason Paul Johnson, Hee-Siew Han, Jacob Scheckman

Patent number: 11486803Abstract: Various embodiments include methods and systems to dilute a sampled particle-laden aerosol stream in a recirculating type of aerosol diluter system. In one embodiment, a system to dilute a sampled aerosol stream includes an aerosol sample inlet. A primary diluter device includes a first inlet to receive the aerosol stream and a second inlet to receive a filtered portion of the aerosol stream and combining the filtered portion with an additional sampled aerosol stream. A flow diverter device splits at least the sampled aerosol stream into a first portion of the sampled aerosol stream and a remaining portion of the sampled aerosol stream. A filter receives the remaining portion of the sampled aerosol stream and provides a filtered aerosol stream to the second inlet of the primary diluter device. Other methods and apparatuses are disclosed.Type: GrantFiled: June 25, 2020Date of Patent: November 1, 2022Assignee: TSI IncorporatedInventors: Jason Paul Johnson, Robert C. Anderson, Jeremy Jens Kolb, Aaron Serafin Avenido, Robert Plautz, Steven Keith Isvik

Patent number: 10732082Abstract: Various embodiments include methods and systems to dilute a sampled particle-laden aerosol stream. In one embodiment, a system to dilute a sampled aerosol stream includes an aerosol sample inlet. A filter is coupled in fluid communication with and in parallel with a flow-monitoring device to receive the sampled aerosol stream from the aerosol sample inlet. The flow-monitoring device is configured to allow for a passage of particles contained in the sampled aerosol stream. A pressure sensor and a temperature sensor monitor the filter and the flow-monitoring device. An output from the filter and the flow-monitoring device may be directed to particle measurement or particle sizing instrumentation. An actual dilution ratio of the output sent to the particle measurement or particle sizing instrumentation is determined based on a nominal flowrate of the flow-monitoring device and thermodynamic properties of a gas comprising the aerosol stream. Other methods and apparatuses are disclosed.Type: GrantFiled: September 14, 2017Date of Patent: August 4, 2020Assignee: TSI IncorporatedInventors: Jason Paul Johnson, Robert Anderson, Jeremy Jens Kolb, Aaron Serafin Avenido, Robert Plautz, Steven Keith Isvik

Patent number: 9222859Abstract: A saturator block assembly that is adapted for use with a condensation particle counter is described. The saturator block assembly is comprised of a member that is at least partially formed from a porous material that is adapted to absorb a working fluid. The saturator block assembly also includes at least one open column formed through the porous member. The open column is parallel with a length of the member and is adapted to emit the working fluid in vapor form from the porous material. The saturator block assembly is further comprised of an outer surface, and is adapted to operate at low pressure or low pressure transient applications. A volume of the porous material is configured so as to reduce the amount of air capable of being trapped in the pores of the porous material during low pressure or low pressure transient applications.Type: GrantFiled: April 12, 2012Date of Patent: December 29, 2015Assignee: TSI, INCORPORATEDInventors: Robert Caldow, Steven William Kerrigan, Jason Paul Johnson, Jacob Hackbarth Scheckman
