1. A digital flowmeter comprising:

  • a vibratable conduit;

    first and second drivers connected to the conduit and operable to impart motion to the conduit;

    first and second sensors connected to the conduit and operable to sense the motion of the conduit;

    a control and measurement system connected between the drivers and the sensors the control and measurement system comprising circuitry to;

    receive a first sensor signal from the first sensor, receive a second sensor signal from the second sensor, generate drive signals based on the first and second sensor signals using digital signal processing, supply the drive signals to the drivers, and generate a measurement of a property of material flowing through the conduit based on the first and second sensor signals;

    wherein the control and measurement system generates different drive signals for the two drivers.
