FIELD: physics.SUBSTANCE: method uses a biased mass flow imbalance value obtained by comparing the sum of incoming mass flow measurement values with the sum of outgoing mass flow measurement values and adding a bias component to obtain the biased mass flow imbalance value. The flow of at least one of the incoming and outgoing streams (12, 14, 16, 18) is adjusted to move the biased mass flow imbalance value towards zero. In addition, pressure measurement (PC) is carried out in the connection and the obtained data are used to adjust the bias component in response to a change in the pressure measurement (PC) relative to a pressure set point (PSP), to reduce the change in said pressure measurement (PC) relative to the pressure set point (PSP).EFFECT: high accuracy of control.16 cl, 3 dwg |
