Multi-variable mass/flow rate transfer device

Abstract

The multi-variable mass/flow rate transfer device is provided with: a differential pressure/static pressure/temperature calculating unit for calculating a differential pressure value, a static pressure value, and a temperature value in real time based upon a signal detected from a process; an instantaneous flow rate calculating unit for calculating an instantaneous flow rate based upon the differential pressure value, the static pressure value, and the temperature value; an accumulation counter for accumulating the calculated instantaneous flow rate of the instantaneous flow rate calculating unit so as to produce an accumulated flow rate; and an accumulated flow rate alarm unit for producing an alarm when the accumulated flow rate produced by the accumulation counter becomes a predetermined value.
