Abstract: A meter electronics (20) for a flowmeter (5) configured to receive a process fluid is provided. The meter electronics (20) includes an interface (201) configured to communicate with a flowmeter assembly of the flowmeter (5) and to receive a vibrational response. The meter electronics (20) comprises a drive gain threshold determination routine (215) configured to determine a first predetermined drive gain threshold (302), monitor a drive gain signal over a predetermined time period, and determine lowest points in the drive gain signal over the predetermined time period. A second drive gain threshold is determined based upon reaching a predetermined number of instances of low points of the drive gain signal.

Abstract: A method and apparatus for operating a flowmeter (5) is provided. A process fluid is placed in the flowmeter (5). A measured mass flow rate (221) of the process fluid is determined. The process fluid is totalized. A first flowmeter parameter is measured. The measured mass flow rate (221) is set to zero if the first flowmeter parameter differs from a pre-determined threshold by a predetermined amount, and totalizing is halted if the first flowmeter parameter differs from a predetermined threshold by a predetermined amount.

Abstract: A mode splitter (300) for a balance bar (150) of a Coriolis flow meter (100) is disclosed. The mode splitter (300) comprises a mass portion (302), and a first coupling portion (304a) coupled to the mass portion (302). The first coupling portion (304a) has a first stiffness in a drive direction (Y) and a second stiffness direction in an orthogonal direction (Z), and the orthogonal direction (Z) is orthogonal to both the drive direction (Y) and a longitudinal direction of the balance bar (150). The second stiffness is different than the first stiffness.

Abstract: A meter electronics (20) for using a stiffness measurement to compensate a fluid property measurement is provided. The meter electronics (20) comprises an interface (601) configured to communicatively couple to a sensor assembly (10) and receive sensor signals from the sensor assembly (10), and a processing system (602) communicatively coupled to the interface (601). The processing system (602) is configured to determine a fluid property value based on the sensor signals and correct the fluid property value with a fluid property correction value, the fluid property correction value being correlated with a current stiffness value of the sensor assembly.

Abstract: A vibratory meter (5) including a multi-channel flow tube (130) is provided. The vibratory meter (5) includes a meter electronics (20) and a meter assembly (10) communicatively coupled to the meter electronics (20). The meter assembly (10) includes the multi-channel flow tube (130, 330, 430, 530) comprising two or more fluid channels (132, 332, 432, 532) surrounded by a tube wall (134, 334, 434, 534). The two or more fluid channels (132, 332, 432, 532) and tube wall (134, 334, 434, 534) comprise a single integral structure. A driver (180) is coupled to the multi-channel flow tube (130, 330, 430, 530). The driver (180) is configured to vibrate the multi-channel flow tube (130, 330, 430, 530). The two or more fluid channels (132, 332, 432, 532) and tube wall (134, 334, 434, 534) are configured to deform in the same direction as the single integral structure in response to a drive signal applied to the driver (180).
