Electromagnetic flowmeter and method of using same

The invention relates to a magnetic flowmeter and a method of using the same. The magnetic flowmeter has a transmitter module that generates a drive signal for driving a magnetic field in a flowing fluid. A flowtube module samples a voltage induced in the fluid by the magnetic field and generates a measurement signal. A single communication path carries the drive signal from the transmitter module to the flowtube module and the measurement signal from the flowtube module to the transmitter module. The flowtube module generates a digital measurement signal. The flowtube module can include a processor for bundling the measurement signal with other information such as calibration data for the flowtube. In addition, the processor can control the timing of flowtube module operations so that the flowtube module samples the induced voltage and transmits the measurement signal to the transmitter module at different times. 本发明涉及电磁流量计及其使用方法。磁性流量计具有生成用于在流动流体中驱动磁场的驱动信号的发送器模块。流管模块对由磁场在流体中感应出的电压进行采样并且生成测量信号。单个信号路径将驱动信号从发送器
