Abstract

A method comprising:inputting a first signal into a flow meter, the first signal corresponding to vibration of a flow tube;compensating for a delay in the first signal, which delay is associated with a digital element associated with the flow meter; and outputting a second signal from the flowmeter, the second signal corresponding to vibration of the flow tube,characterized in that compensating for the delay of the first signal comprises:inputting the second signal from an output of the flowmeter to an input of the flowmeter;comparing the second signal with the first signal to determine a phase difference between the second signal and the first signal; and outputting a revised second signal from the flow meter that is balanced to the second signal based on the phase difference,wherein the first signal includes a first sensor signal associated with a first sensor and a second sensor signal associated with a second sensor, and the second signal first driver signal associated with a first driver and a second driver signal associated with a second driver, and where in comparing the second signal to the first signal comprises:receiving the first sensor signal and the first driver signal at a first multiplexer;outputting a first multiplexed signal from the first multiplexer;receiving the second sensor signal and the second drive signal at a second multiplexer;outputting a second multiplexed signal from the second multiplexer; and comparing the first multiplexed signal and the second multiplexed signal to thereby determine the phase difference..
