Abstract

A system for determining at least one calculated process parameter of a fluid in a pipe includes a data interface receiving nominal process parameters, which relate to nominal parameters of a process that relates to the fluid in the pipe; an invasive temperature sensor that determines a fluid temperature; a reference temperature sensor disposed outside of the pipe for determining a reference temperature; a surface temperature sensor disposed at a surface of the pipe for determining a surface temperature; a process model that determines a process parameter by using the reference temperature, the surface temperature, the received nominal process parameters, and the determined fluid temperature.
