Abstract: A system (800) for minimizing a crest in a multi-tone drive signal in a vibratory meter (5) is provided. The system (800) includes a drive signal generator (810) configured to generate the multi-tone drive signal for the vibratory meter (5) and a drive signal detector (820). The drive signal detector (820) is configured to receive the multi-tone drive signal, determine a first maximum amplitude of the multi-tone drive signal having a component at a first phase, determine a second maximum amplitude of the multi-tone drive signal having the component at a second phase, and compare the first maximum amplitude and the second maximum amplitude.

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).

Abstract: A vibratory cavity density meter (100-300) is provided. The vibratory cavity density meter (100-300) includes a pipe (110-310) extending from a first end (110a-310a) to a second end (110b-310b). The first end (110a-310a) includes an aperture (114-314) configured to receive a material from a container (10) and the second end (110b-310b) is self-enclosed so as to contain the material in the pipe (110-310). The vibratory cavity density meter (100-300) also includes at least one transducer (118, 218) coupled to the pipe (110-310), the at least one transducer (118, 218) configured to one of induce and sense a vibration in the pipe (110-310) to measure a property of the material.

Abstract: A method for determining a lateral mode stiffness of one or more fluid tubes (103A, 103B) in a vibrating meter (5) is provided. The method comprises a step of vibrating at least one of the one or more fluid tubes (103A, 103B) in a drive mode vibration. Drive mode sensor signals (310) are received based on a vibrational response to the drive mode vibration. At least one of the one or more fluid tubes (103A, 103B) is vibrated in a lateral mode vibration, wherein the lateral mode is approximately perpendicular to the drive mode. Lateral mode sensor signals (317) are received based on a vibrational response to the lateral mode vibrations. The method further comprises determining a lateral mode stiffness (318) based on the lateral mode sensor signals (317).
