A method for improving flowmeter (5) reliability is provided. The flowmeter (5) has at least one flow tube (130, 130′), at least one pickoff sensor (170L, 170R) attached to the flow tube (130, 130′), at least one driver (180L, 180R) attached to the flow tube (130, 130′), and meter electronics (20) in communication with the at least one pickoff sensor (170L, 170R) and driver (180L, 180R). The method includes the steps of vibrating at least one flow tube (130, 130′) in a drive mode vibration with the at least one driver (180L, 180R), and receiving a sensor signal based on a vibrational response to the drive mode vibration from the at least one pickoff sensor (170L, 170R). At least one flow variable is calculated. A pickoff sensor voltage is measured, and it is determined whether the pickoff sensor voltage is below a predetermined voltage threshold (304). The at least one flow variable is corrected during periods wherein the pickoff sensor voltage is below the predetermined voltage threshold (304).
A method for improving flowmeter reliability, wherein the flowmeter comprises at least one flow tube, at least one pickoff sensor attached to the flow tube, at least one driver attached to the flow tube, and meter electronics in communication with the at least one pickoff sensor and driver, comprising the steps of:
Meter electronics (20) for a flowmeter (5) configured to improve measurement reliability, wherein the flowmeter (5) comprises:
