Abstract
The invention relates to meter electronics () for vibratory flowmeter friction compensation is provided. The meter electronics () includes an interface () configured to communicate with a flowmeter assembly () of a vibratory flowmeter () and receive a vibrational response and a processing system () coupled to the interface () and configured to measure a mass flow rate of a fluid using the vibrational response. The processing system () is configured to determine a fluid velocity (V) using the mass flow rate, a fluid density (p), and a cross-sectional flow area (A), determine a friction factor (f) using the fluid velocity (V) and a pressure drop (ΔP), and determine a compensation factor using the friction factor (f). The invention also relates to a vibratory flowmeter compensation method.
