  • Patent number: 8239157
    Abstract: A method and apparatus is disclosed that guides a user through a sequence of steps that will allow the user to complete a predefined task using the flow meter. The steps include: selecting a predefined task, displaying a sequence of steps that directs the user through a process for using the Coriolis flow meter to complete the predefined task, and operating the Coriolis flow meter in response to the sequence of steps to complete the predefined task.
    Type: Grant

  • Patent number: 5497666
    Abstract: An increased sensitivity Coriolis flowmeter having one or more drivers oscillates a flow tube, or tubes, at pre-determined frequencies thereby producing active and/or static nodes at points along the flowtube(s). The increased sensitivity of the present flowmeter is provided by controllably locating sensors in close proximity to the static nodes and/or active nodes. In a first embodiment, the flowtubes are oscillated in a manner generating a single active node with sensors positioned in close proximity to, and on opposing sides of, the active node. In a second embodiment, the flowtubes are oscillated in a manner generating multiple active nodes where the sensors are located on opposing sides of each active node, or on opposing flowtubes where one sensor is above an active node on one leg and a second sensor below the active node on the opposing leg. In another embodiment, sensors are positioned in close proximity to static nodes in addition to the sensor positions for active nodes as previously stated.

  • Patent number: 5370002
    Abstract: A Coriolis effect mass flow meter having a brace bar of improved flexibility which reduces the stress concentration in a brace bar as well as in areas of meter's flow tubes proximate the brace bar and flow tubes of the flow meter. A brace bar means is disclosed that has a void in an area between its holes that receive the flow tubes. This void increases the flexibility of the brace bar and shifts the concentration of operational and manufacturing induced stresses away from the braze joints between the brace bar and the flow tubes. The stresses are reduced and shifted away from the flow tubes to an area within the brace bar that is less critical to the overall life and reliability of the flow tubes. Meter sensitivity is improved due to enhanced flexibility of the present invention's brace bar in response to the motion induced by the Coriolis effect.

  • Patent number: 5344717
    Abstract: A method of brazing and apparatus therefor wherein two elements are bonded together using pre-formed fillet material. In accordance with a first alternative embodiment, the pre-formed fillet material comprises a depression formed on a first surface of one of the elements by a punching operation. The preformed fillet material also comprises a protrusion formed on a second surface opposite the depression formed by the punching operation. The invention also comprises a method of reducing bending stress in a Coriolis flow tube by bonding the flow tube and a brace bar with preformed fillet material.
