FIELD: measurement equipment.
SUBSTANCE: invention relates to the system and method to measure fluid medium flow. A vibration flow meter (5) comprises a sensor assembly located in a pipeline (301). The sensor assembly (10) is in connection by means of fluid medium with one or more switches (309) of fluid medium. A measurement electronic circuit (20) is made as capable of measurement of one or more characteristics of fluid medium flow flowing via the sensor assembly (10). The measurement electronic circuit (20) is additionally made as capable of receiving the signal (214) of the first switch of fluid medium, indicating the condition of the fluid medium in the pipeline (301), from the first switch (309) of the fluid medium from one or more switches of fluid medium. The measurement electronic circuit (20) is additionally made as capable of correction of one or more characteristics of the flow, if condition of the fluid medium is outside the limits of the threshold value or range. The switch (309) of fluid medium represents a switch of the level of the fluid medium, besides, the signal (214) of the first switch of the fluid medium indicates that the level of fluid medium in the pipeline (301) goes outside the limits of the threshold value or range; or the switch of the flow of the fluid medium, besides, the signal (214) of the first switch of the fluid medium indicates that the flow of the fluid medium via the pipeline (301) goes outside the limits of the threshold value or range.
EFFECT: increased accuracy.
