Abstract

A vibrating meter (5) is provided. The vibrating meter (5) includes one or more conduits (103A, 103B) including a vibrating portion (471) and a non-vibrating portion (472) and a driver (104) coupled to a conduit of the one or more conduits (103A, 103B) and configured to vibrate the vibrating portion (471) of the conduit at one or more drive frequencies. The vibrating meter (5) also includes one or more pick-offs (105, 105') coupled to a conduit of the one or more conduits (103A, 103B) and configured to detect a motion of the conduit. One or more meter components exclusive of the vibrating portion (471) of the conduits (103A, 103B), the driver (104), and the pick-offs (105, 105') is provided with a damping material (310) applied to at least a portion of a surface of a meter component of the one or more meter components that reduces one or more vibrational resonant frequencies of the meter component below the one or more drive frequencies.

Description

technical field [0001] The present invention relates to vibrating meters, and more particularly to vibrating meter components having damping material applied to the surface of the metering component. Background technique [0002] Vibration meters such as density meters, volume flow meters and Coriolis flow meters are used to measure one or more properties of materials such as density, mass flow rate, volume flow rate, total mass flow rate, temperature and other information. The vibrating meter includes one or more conduits, which can have various shapes such as straight, U-shaped or irregular structures. [0003] One or more pipelines have a set of inherent modes of vibration including modes such as simple bending, torsional, radial and coupled vibrations. In order to determine the properties of the material, one or more conduits are vibrated by at least one drive at a resonant frequency in one of these modes, hereinafter referred to as drive mode. One or more meter electr...
