摘要： Flow meter electronics are described for providing a flow rate of a material flowing through a flow meter sensor of a Coriolis flow meter. The flow meter electronics comprise a processing system and a single output port. The processing system receives pick-off signals from the flow meter sensor and processes the pick-off signals to determine the flow rate. The processing system receives an instruction for a frequency output signal or a digital communication protocol signal. If the instruction is for a frequency output signal, then the processing system processes the flow rate to generate a frequency output signal and transmits the frequency output signal over the single output port. If the instruction is for a digital communication protocol signal, then the processing system processes the flow rate to generate a digital communication protocol signal and transmits the digital communication protocol signal over the single output port.

摘要： A system for setting baud rate and communication protocol in a remote device. In this invention, the remote device receives samples of signals from a host device in a buffer. The remote device then detects a baud rate of said signals from the samples. A protocol being used by the host device to communicate is also determined from the samples. The remote device is then set to communicate using the determined protocol at the detected baud rate.

摘要： An apparatus and method for deterministically communicating data between multiple nodes in a fashion that is consistent with the Controller Area Network ("CAN") communications protocol. The system applies to multiple nodes that functional blocks within an operating system environment and to multiple nodes that are each connected to a serial bus. The system utilizes standard CAN error checking, bus arbitration and message formatting and therefore uses standard CAN controllers and transceivers. One node on the bus is selected as the master node. The master node issues a periodic synchronization signal which defines time divisions within which the operations of each node and communications over the CAN bus are organized. Data, particularly real-time data, is transmitted between nodes on the CAN bus during a known time division. Standard CAN bus arbitration is used to ensure that real-time data is transmitted over the CAN bus prior to the transmission of non-real-time data. This ensures that real-time data is, if appropriate, transmitted during each time division.

摘要： An analog-to-digital conversion stage (300) includes three or more ADCs (303, 305, 307) that receive two or more analog signals, generate a first digitized signal from a first analog signal, generate at least a second digitized signal from at least a second analog signal to create two or more digitized signals, and generate one or more redundant digitized signals from the two or more analog signals. The one or more redundant digitized signals are generated substantially in parallel with the two or more digitized signals. A processing device (330) generates a phase drift value from a phase difference between a redundant digitized signal of the one or more redundant digitized signals and a corresponding digitized signal of the two or more digitized signals and compensates the corresponding digitized signal using the one or more phase drift values.

摘要： A method and apparatus for operating a vibrating flow meter is provided. The method comprises the steps of receiving sensor signals from the vibrating flow meter and determining a current zero offset for the vibrating flow meter. The current zero offset can be determined based on the received sensor signals. The method also comprises the step of determining one or more current operating conditions. The one or more current operating conditions can be compared to one or more previous operating conditions of the offset correlation. The method also includes the step of generating an average zero offset if the offset correlation includes a previously determined zero offset corresponding to the current operating conditions. The average zero offset can be based on the current zero offset and the previously determined zero offset.
