Abstract
In this invention, a multivariable transmitter providing an output representative of mass flow has a dual microprocessor structure. The first microprocessor compensates digitized process variables and the second microprocessor computes the mass flow as well as arbitrating communications between the transmitter and a master. In a second embodiment of the present invention, a first microprocessor compensates digitized process variables, a second microprocessor computes an installation specific physical parameter such as mass flow and a third microprocessor arbitrates real-time communications between the transmitter and a master.
