VIBRATING TUBE DENSIMETER

摘要

A Coriolis effect densimeter which produces density output data of improved accuracy by embodying the principal that the natural frequency of a vibratin g tube filled with material decreases with an increase in the material mass fl ow rate. High accuracy output data is achieved by measuring the density and the mass flow rate of material through the vibrating tube, correcting the measur ed density to compensate for the effect of the mass flow rate, and correcting t he mass flow rate correction of the density measurement for changes due to temperature.
