Patent number: 10254143Abstract: A fluid-flow sensor assembly is provided, comprising a body defining a measuring region for fluid flowing therethrough. A rigid structure is defined about the body to restrict size variation of the body during use. As a result, the rigid structure keeps the measuring section from altering in size, thus ensuring accurate measurement. In an exemplary embodiment, the body defines a ridge assembly that circumscribes the outer wall of the body, and a spiral wrap formed of rigid material is wrapped around the body.Type: GrantFiled: January 13, 2017Date of Patent: April 9, 2019Assignee: Georg Fischer Signet LLCInventors: Gert Burkhardt, Jorge Samayoa

Patent number: 8336375Abstract: A flow cell assembly for fluid sensors is provided. The assembly includes a housing configured to couple to an external source of fluid for measurement. The assembly further includes a flow regulator and a flow meter disposed within the housing to facilitate controlled fluid. The housing defines one or more measuring chambers each configured to receive a fluid sensor. Each measuring chamber includes an inlet aperture and a gravity overflow spaced apart from the inlet aperture. Each measuring chamber is configured to receive a fluid sensor such that a sensing end of the fluid sensor is disposed proximate to an inlet aperture of the measuring chamber, thereby ensuring controlled fluid pressure proximate to the sensing end.Type: GrantFiled: June 18, 2010Date of Patent: December 25, 2012Inventors: Anthony Thai, Steven Wells, Gert Burkhardt

Patent number: 8317989Abstract: An electrochemical sensor is provided that includes a housing having an outer wall, an axial bore circumscribed by the outer wall, and a barrier wall that aids in defining a reference cavity. The housing further including a plurality of cross members in spaced relation to one another disposed between the axial bore and the outer wall, each cross member defining an aperture.

Patent number: 7550979Abstract: A system and related method are provided to calibrate for wire capacitance during use to minimize error in conductivity measurement of the target fluid. The system includes a signal generator configured to drive the conductivity cell and the temperature element, with an alternating current (AC) drive signal having variable parameter. The system further includes a processor assembly electrically coupled to the conductivity cell and the temperature element to calculate a conductivity value of the fluid. The conductivity value is a function of the values of the temperature measurement, the compensation measurement, and the raw conductivity measurement, thereby compensating the conductivity value for capacitance effects. In this manner, the system effectively compensates for capacitance attributable to wiring extending between the electrode and other electronics of the sensor, usable with wiring of varied and unknown lengths.Type: GrantFiled: May 29, 2007Date of Patent: June 23, 2009Assignee: Georg Fischer Signet LLCInventors: Qinming Zhou, Gert Burkhardt
