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.
