Method for determining a characteristic variable of process medium e.g. for crude oil for petroleum processing, requires evaluation program capable of operating in sensor connected to data bus

摘要

A method for a characteristic variable of a process medium involves an evaluation program which can independently communicate with defined communications sections, so that it can operate in one of the sensors (S1,S2,S3,S4) connected to the data bus or in a further unit joined to the data bus.
