Abstract: Systems, methods, and devices are provided for a removable sensor adaptor for an end flange of a blind tee. Such a system may include a flange to be installed on a blind tee conduit and a removable sensor adaptor to be installed in the end flange. The sensor adaptor may be removed from the flange without removing the flange from the blind tee.

Abstract: Methods and apparatus for calibrating microwave reflection sensors in fluid flow measurement devices are described. A calibration apparatus has a reservoir member with a fill opening, the reservoir member defining a reservoir in an interior thereof, the fill opening being operable to fill the reservoir with a calibrant fluid; a tube coupled to a side of the reservoir member and in fluid communication with the reservoir, the tube having a first end coupled to the side of the reservoir and a second end, the tube having a length matched to an inner diameter of a pipe section of the flow measurement device to extend across the inner diameter; and a seal member disposed at the second end of the tube for scaling the second end of the tube against a sensing surface of the microwave reflection sensor installed in the pipe section of the flow measurement device.

Abstract: Electromagnetic probes for analyzing a flowing multi-phase fluid are described herein. The probes generally use a probe assembly for measuring liquid properties in a multiphase fluid flowing in a conduit, the probe assembly comprising a first member with a probe portion and a connection portion, the probe portion having a central bore with a conductor and a pressure-resistant insulator surrounding the conductor, the conductor extending from an opening at a distal end of the probe portion into the connection portion, the connection portion having a connector coupled to a distal end of the connection portion, the connection portion having a seal face with a groove extending around the probe portion; and a second member that, when assembled, is in direct contact with the first member at the distal end of the connection portion to apply compression and to retain the first member against a wall of the conduit.

Abstract: Multiphase flowmeter aperture antenna transmission and pressure retention are disclosed herein. An example apparatus includes at least one radiating element to transmit or receive an electromagnetic signal along a measurement plane orthogonal to a direction of flow of the fluid in the vessel; a pressure retaining member to prevent fluid from entering the aperture antenna assembly through a measurement window of the aperture antenna assembly, at least a portion of the pressure retaining member to separate the radiating element and the fluid; and a metal housing with or without slits, the pressure retaining member to be at least partially within the metal housing, the radiating element to be coupled to the metal housing.
