Abstract

A vibratory meter (5, 1600) configured to predict and reduce noise in the vibratory meter (5, 1600). The vibratory meter (5, 1600) includes a sensor assembly (10, 1610) and a meter electronics (20, 1620) in communication with the sensor assembly (10, 1610). The meter electronics (20, 1620) is configured to provide a drive signal to a sensor assembly (10, 1610), receive a sensor signal from the sensor assembly (10, 1610) having one or more components, and generate a signal to be applied to one of the sensor signal and the drive signal to compensate for the one or more components.

Description

technical field [0001] The embodiments described below relate to noise in sensor signals in vibrating meters, and more particularly, to predicting and reducing noise in vibrating meters. Background technique [0002] Vibrating meters such as, for example, Coriolis mass flow meters, liquid density meters, gas density meters, liquid viscometers, gas / liquid pycnometers, gas / liquid relative density meters and gas molecular weight meters are generally known And used to measure the properties of the fluid. Typically, a meter includes a sensor assembly and an electronics section. The material within the sensor assembly can be flowing or stationary. Each type of sensor can have unique characteristics that must be considered for optimal performance of the meter. For example, some sensors may require the tube equipment to vibrate at a specific level of displacement. Other sensor component types may require special compensation algorithms. [0003] Meter electronics typically incl...
