Each successive one of the turbulence generator elements increases in number and decreases in scale of its respective set of fluid flow passages with respect to the previous one of the turbulence generator elements in a substantially multi-scale pattern. The set of turbulence generator elements is positioned within a fluid flow conduit, and each of the turbulence generator elements is spaced apart from adjacent ones of the turbulence generator elements in a multi-planar arrangement such that the turbulence generation in fluid flow optimizes some turbulence property and/or its effects with an improved effective grid blockage ratio. The turbulence generator elements are selectively positionally adjustable for active control of turbulence in response to varying conditions.Type: GrantFiled: May 12, 2015Date of Patent: March 21, 2017Inventor: Nadeem Ahmad Malik

Patent number: 9518968Abstract: An in situ oxygen analyzer having an intrinsically-safe output and a heated probe is provided. The probe is extendable into a source of process gas and has an oxygen sensor and heater disposed therein. The heater is configured to heat the oxygen sensor to a temperature sufficient to operate the oxygen sensor. A housing is coupled to the probe and has first and second chambers. The first chamber is explosion-rated and includes non-intrinsically safe circuitry coupled to the heater to energize the heater. The second chamber contains only intrinsically-safe circuitry that complies with an intrinsically-safe specification. The first and second chambers are isolated from one another. The non-intrinsically-safe circuitry is coupled to the intrinsically-safe circuitry through an energy-limiting isolator.Type: GrantFiled: May 12, 2014Date of Patent: December 13, 2016Assignee: Rosemount Analytical Inc.Inventors: Joseph C. Nemer, Mark D. Stojkov
