PROGRAMMABLE CORIOLIS FLOW METER ELECTRONICS FOR OUTPUTTING INFORMATION OVER A SINGLE OUTPUT PORT

摘要

Flow meter electronics (302) are described for providing a flow rate of a material flowing through a flow meter sensor (10) of a Coriolis flow meter (300). The flow meter electronics (302) comprise a processing system (304) a nd a single output port (306). The processing system (304) receives pick-off signals from the flow meter sensor (10) and processes the pick-off signals t o determine the flow rate. The processing system (304) 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 (304) processes the flow rate to generate a frequency output signal and transmits the frequency output signal over the single output port (306). If the instruction is for a digital communication protocol signal, then the processing system (304) processes the flow rate to generate a digital communication protocol signal and transmits the digital communication protoc ol signal over the single output port (306).
