Conclusion
The above considerations show that until reliable data are available there is no point in including in the All-Union standard specification for measuring flows a recommendation for evaluating the error in measuring pulsating flows by means of the damping criterion and to classify the differential manometers combined with constricting devices among instruments with standardized errors.
Differential manometers can be used in pulsating flows only as indicators of the flow (instruments with a nonstandard error). In this connection the instructions embodied in Regulations 27–54 and referring to the measurement of pulsating flows should be revised.
