Abstract:
Flow meters sensitivity to their operation conditions is a key issue to both flow meters manufacturers and end users. This study gives an explanation to experimental and performance investigation of the installation effects on the venturi flow meter. Therefore, the aim of this study is to determine the dynamic change effects of the venturi meter reading resulting from distorted and abnormal flow meter internal conditions and to reduce economic losses associated with it during industrial applications. To achieve the aim of the study, an experimental investigation was carried out using H5 bench venturi flow meter, in order to characterize the measurement of flow rate in a pipe and to compute better coefficient of discharge, air flow rate, and flow coefficient. Obtained results show that distorted flow conditions can amount to significant errors up to �7.5 percent; but in this work, the coefficient of discharge has been reduced to �6-�1.2 percent. It is also established that fluid carrying tiny particles of impurities causes pressure build-up at the tap�s head, leading to dynamic flow development. The experimental results have been dynamically presented in terms of the measured air flow rate, flow coefficient, and coefficient of discharge. The results depicted that the error caused by the internal conditions of the distorted-abnormal flow meter which could lead to significant economic losses were reduced to the barest minimum. The venturi meter analyses show the relationship between pressure losses and variation of pressure and velocity at different cross-sectional area of the piping system used in transportation of fluid especially in the oil and gas industry.
