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.

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