DESIGN OF AN ACCURATE CORIOLIS METER SYSTEM USING A DENSOMETER

Abstract

The Coriolis meters are considered as one of the most important meters to measure the flow rate as well as the density. However, a common complaint from petroleum companies is always rises regarding the accurate measurement of the delivered volume. The lack of accurate measuring of volume is because of the effect of density and other external design factors, in this thesis, an analysis of the existing measuring system has been done, a newly design meter has been proposed and simulates using WinCC. The simulation results shows that the proposed design enhances the accuracy of the existing one, this enhancement has been done by the use of external Densometer to rectify the error in density measurement, which leads to enhancement of the accuracy in volume measurement. The control of density has been done by the addition of an external Densometer which introduces some amendments to the basic striation by added Densometer and modifying the software to be able to control the density in specific rang which is representation in the simulation. The result from proposed design agrees with the previous works regarding the effect of density in measuring the volume of petroleum product. Moreover, the readings of the enhanced meter show the impact of the amendments, to the performance of the meter, by reducing losses and gain in the result. Furthermore, the readings have been compared with the typical simulated design of the existing meter and it is promising.
