Abstract:
1. A multivariable transmitter comprising: a single microprocessor for executing a plurality of computation processing tasks using a plurality of physical quantity signals; and an output section for outputting an output of said multivariable transmitter, wherein the single microprocessor executes the plurality of computation processing tasks in a time-division manner, wherein every computation processing task is not executed during every computation processing period, such that high priority computation processing tasks are executed more frequently than low priority computation processing tasks, the computation processing tasks include a computation processing task for calculating a differential pressure value and a static pressure value of a fluid to be measured, and a flow rate computation processing task based on the differential pressure value, the static pressure value and a temperature value of the fluid to be measured; and wherein the computation processing tasks include a computation selecting processing which selects a processing item to be executed during each computation period, and a process temperature value computation processing task to be divided and executed through a plurality of computation periods, and the temperature value of the fluid to be measured is a process temperature with respect to the fluid to be measured.
