Abstract

A method for temperature compensation of a signal in a vibratory meter is provided. The method includes obtaining one or more signals from a meter assembly in the vibratory meter, providing the one or more signals to a meter electronics of the vibratory meter, and compensating the one or more signals with a signal parameter offset, wherein the signal parameter offset is based on a temperature of the meter electronics.

Description

technical field [0001] Embodiments described below relate to temperature compensation of signals from vibrating structures, and more particularly, to temperature compensation of signals in vibrating meters. Background technique [0002] Sensors are often used to measure the motion of objects. For example, vibrating meters typically use sensors to measure the position, velocity or acceleration of the tube. In particular, a vibrating meter may use a driver to vibrate a tube filled with a material such as a fluid. Sensors can measure the motion of the tube to determine the properties of the fluid in the tube. For example, a sensor may be coupled to a tube filled with material proximate to a first fluid port, and a second sensor may be coupled to a tube filled with material proximate to a second fluid port. The time delay between the first and second sensors may be proportional to the flow rate of the material. The time delay may be determined from the two signals provided...
