摘要:
A flowmeter is provided that includes a sensor assembly and meter electronics. The flowmeter comprises two or more flow tubes, a driver coupled to the flow tubes that is oriented to induce a drive mode vibration in the flow tubes. Two or more strain gages are coupled to the two flow tubes and oriented to detect the phase of the drive mode vibration. One or more bridge circuits is in electrical communication with the two or more strain gages, wherein the bridge circuits are configured to output a signal indicating an asymmetric flow between the two flow tubes.
