The effects of flow pulsation on, meter response are to be investigated for both turbine and Coriolis flowmeters. In small turbinemeters for liquid flows, the coupling of fluid inertia with the meter rotors produces behaviour significantly different from that found with gas flows. meter response to accelerating and decelerating flows is asymmetrical and in flows with sinusoidal flow pulsations this results in the meter reading erroneously high. This feature is likely to be practical significance for small diameter meters only. A theoretical model of the meter dynamic response will be developed ad then evaluated by experiment. Procedures will be developed for the correlation of both mean and dynamic flow component measurements.Flow measurement by the Coriolis principle is based o a flow conduit which is extremely excited to vibrate at one of a number of possible modes of resonance. Flow pulsations at a frequency close to one of the conduit resonant frequencies have the potential for a coupling effect which could be highly disruptive. A theoretical model of this coupling will be developed and meter response evaluated experimentally for three differing meter geometries. Because of the wide range of flow conduit geometries in use the likely project output is strategy for predicting potentially disruptive modes of reasonance and determination of the corresponding resonant frequencies.
