FIELD: physics. ^ SUBSTANCE: device for regulating flow of a process fluid includes a power supply module, a process communication circuit, a processor and a measuring circuit. The process communication circuit is connected to the power supply module and the processor. The measuring circuit is operationally connected to a plurality of process parameter sensors for obtaining indication of differential pressure, static pressure and temperature of the process fluid. The processor is configured to calculate mass flow of the process fluid and use static pressure and temperature of the process fluid to obtain the value of energy per unit mass of the process fluid and to enable indication of energy flow. ^ EFFECT: possibility of calculating energy flow and high accuracy of regulating flow of a process fluid. ^ 12 cl, 3 dwg |
