A method and apparatus is disclosed that determines the time delay () between the actual flow and the measured flow in a flow meter. The time delay is used to shift the flow measured by the flow meter to correspond to the actual flow measured by a prover or calibration system. In this way an accurate comparison is made between the flow measured by the flow meter and the flow provided by the prover.

A Coriolis flow meter includes first and second pickoff sensors, cabling coupled to the first and second pickoff sensors, and a signal injection device coupled to the cabling. The signal injection device is configured to generate one or more reference signals, with the one or more reference signals being substantially identical in phase, and communicate the one or more reference signals into the cabling and the first and second pickoff sensors. The Coriolis flow meter further includes a signal conditioning circuit coupled to the cabling. The signal conditioning circuit is configured to receive first and second response signals from the cabling and the first and second pickoff sensors in response to the one or more reference signals and determine a signal difference between first and second response signals.

To increase power to a measurement device, the measurement device measures a first voltage across the measurement device. The measurement device then determines an operating current based on the first voltage. The operating current is a maximum current that the measurement device draws without dropping a measurement device voltage below a threshold voltage to prevent resetting of the measurement device. The measurement device then generates a signal to change the power to use the operating current.

A system for initializing parameters of a transmitter connected to a Coriolis flowmeter. This invention applies initial drive signals to a drive circuit which causes a flow tube to vibrate. The type of the flow tube is then determined from signals received from pick-off sensors associated with the flow tube. Parameters for generation of said drive signals are then set based upon the type of said flow tube.
