1. A flowmeter comprising:
- a vibratable conduit;
a driver connected to the conduit and operable to impart motion to the conduit;
a sensor connected to the conduit and operable to sense the motion of the conduit; and
a control and measurement system connected to the driver and the sensor, the control and measurement system comprising circuitry to;
receive a sensor signal from the sensor, detect a change in density, generate a drive signal based on the sensor signal to correct for the change in density, supply the drive signal to the driver, and generate a measurement of a property of material flowing through the conduit based on the sensor signal.

Abstract
A flowmeter includes a vibratable conduit, a driver connected to the conduit and operable to impart motion to the conduit, and a sensor connected to the conduit and operable to sense the motion of the conduit. A control and measurement system is connected to the driver and the sensor. The control and measurement system includes circuitry to receive a sensor signal from the sensor, generate a drive signal based on the sensor signal, supply the drive signal to the driver, and generate a measurement of a property of material flowing through the conduit based on the sensor signal.
