Determining and identifying anomalies in fork meters

A method for operating meter electronics to determine a presence of a process anomaly in a fluid flow system, comprising:

• providing a meter having a vibratory sensor in communication with the meter electronics, wherein the vibratory sensor comprises vibratory elements operable to be immersed in a fluid of a fluid flow, wherein the vibratory element comprises tines, wherein the vibratory element is coupled to the meter electronics, and wherein the meter electronics is configured to provide a drive signal to a driver that induces vibrations in the vibratory element, and receive a vibratory signal from at least one sensor that measures the vibrations of the vibratory element;
• interfacing a data processing circuit with the meter electronics;
• determining, using the data processing circuit, a measured density of the fluid in the fluid flow system;
• determining, using the data processing circuit, whether the fluid flow system is experiencing a density anomaly based on a relationship between the measured density and an expected density of the fluid in the fluid flow system;
• determining, using the data processing circuit, a measured phase difference of vibrations of the vibratory elements of the meter;
• determining, using the data processing circuit, whether the fluid flow system is experiencing a phase anomaly based on a relationship between the measured phase difference and a target phase difference of the vibrations of the vibratory elements in the fluid flow;
• identifying, using the data processing circuit, an anomaly of the fluid flow system based on the determination of whether there is a density anomaly and the determination of whether there is a phase anomaly;
• and
• responding to the anomaly, using the data processing circuit, by one or more of, notifying a user of the gas entrainment anomaly, indicating on a meter that the gas entrainment anomaly has occurred, changing the characteristics of the fluid or fluid flow in response to the gas entrainment anomaly, and storing data representing the gas entrainment anomaly.
