    Abstract: A coaxial guided wave radar apparatus includes a central conductor configured as a wire rope. One or more spacers can be positioned and held in place about the central conductor at predetermined lengths along the central conductor, wherein each spacer is positioned and held in place along the central conductor by one or more respective retainers that are crimped to the central conductor. A tensioner can be attached to the end of the wire rope of the central conductor. The tensioner allows for a proper tension to be applied to maintain a spacing of the wire rope from an outer conductor.

    Abstract: A coupling device for coupling a threaded feed-through of a process connection to provide a launcher for a non-metallic storage tank. The storage tank includes a tank aperture in its top surface. The coupling device includes a foil nozzle including an inner upper metal foil surface that includes a threaded aperture for securing the feed-through thereto, and a first and second lower metal foil surface on respective sides of the upper metal foil surface. The foil nozzle also includes a first and a second foil level transition region disposed between the respective sides of the inner upper metal foil surface and the first and second lower metal foil surface. The foil nozzle can be configured in a cylindrical, horn, or a corrugated horn shape.

    Abstract: A dual-optical displacement sensor system includes a scanner including a first and second scanner head including optical displacement sensors providing a first and second beam having a first optical axis (OA) and a second OA. A computing device or programmed circuit is coupled to receive time versus position data from measurements involving alignment target(s) including at least one knife edge pair including a first and second knife edge oriented in a first plane of the alignment target that is essentially perpendicular to the OAs positioned between the scanner heads for interacting with the beams, and implement at least one equation to analyze the data for determining a degree of alignment of the first and second OA. Using the degree of alignment, an algorithm is for automatic alignment of the OAs or assist instructions for a user alignment of the OAs that provides guiding steps for the user for the alignment.

    Abstract: A guided wave radar fluid level measurement system can measure the level of product in a tank. A pulse of RF energy sent along a waveguide in the tank can be reflected where the waveguide enters the product. A time of flight measurement can indicate the product level. The product inside the tank can flow and that flow can push the waveguide and thereby torque and possibly bend the waveguide. A streamlined wave guide is torqued less when the streamlining is aligned with the direction of flow. A rotating connector can provide for the waveguide to rotate and a weathervane effect can align the streamlined waveguide with the flow.

    Abstract: A guided wave radar (GWR)-based method of measuring steam pressure includes transmitting at least a first microwave pulse signal from a GWR sensor system having a pulsed radar gauge (PRG) implementing a steam measurement algorithm coupled to a transceiver that is coupled to a GWR probe in a steam boiler tank having a reference reflector (RR) providing an impedance discontinuity. The transmitting the first microwave pulse signal is with water and steam in the steam boiler tank. An echo emanating from the RR is received responsive to the first microwave pulse signal generates that respective time of flight (TOF) measurement data. A refractive index value for the steam is determined from the TOF measurement data and a reference TOF value representing a TOF measurement without the steam in the steam boiler tank. A physical property of the steam is determined from the refractive index value, such as the pressure.

    Abstract: A measurement apparatus for weight measuring composite sheet including a sheet material having a second material thereon as a coating and/or as embedded particles therein. The apparatus includes an x-ray sensor for providing an x-ray signal from x-ray irradiating the composite sheet and an infrared (IR) sensor for providing an IR signal from IR irradiating the composite sheet. A computing device is coupled to receive the x-ray signal and the IR signal that includes a processor having an associated memory for implementing an algorithm, where the algorithm uses the x-ray signal and the IR signal to compute a plurality of weights selected from a weight of the sheet material, a weight of the second material, and a total weight of the composite sheet.
