ABSTRACT:
A Coriolis effect densimeter which produces density output data of improved accuracy by embodying the principal that the natural frequency of a vibrating tube filled with material decreases with an increase in the material mass flow rate. High accuracy output data is achieved by measuring the natural frequency of the tube as material flows therethrough, correcting the measured frequency to compensate for the decrease in natural frequency caused the material flow (mass flow rate) and using the corrected natural frequency in the material density computation.
