A process fluid flow device includes a power supply module, a process communication module, a processor and measurement circuitry. The process communication circuitry is coupled to the power supply module and to the processor. The measurement circuitry is operably coupleable to plurality of process variable sensors to obtain an indication of differential pressure, static pressure and process fluid temperature. The processor is configured to compute process fluid mass flow, and to use the static pressure and process fluid temperature to obtain an energy per unit mass value relative to the process fluid and to provide an energy flow indication. |
