THEORY OF A CORIOLIS MASS FLOWMETER INSERTION PROBE
Lynn A Hendry, John Hemp
Abstract:
A novel Coriolis mass flowmeter insertion probe concept is described suitable for the measurement of the mass flow of liquids flowing in pipes. It is generally similar to that of the turbine meter insertion probe for volume flow measurement except that the turbine is replaced by a small vibrating aerofoil of elliptical cross-section. The weight vector theory of Coriolis mass flowmeters is applied to predict the approximate sensitivity of the probe. The sensitivity so predicted can be comparable to that of commercial (vibrating tube) Coriolis mass flowmeters so that the signal processing techniques developed for these could be directly used in conjunction with the proposed insertion meter. The dependence of sensitivity on Reynolds number and on liquid density is discussed and a way of removing dependence on liquid density is described.
