    Electric Control and Meterological Validation of Sensors in Dynamic Metering System of Fluids

    No full text
    The verification method of a metering system varies from one site to another, depending on the available equipment and the calibration equipment measuring instruments installed. However, the effectiveness of the verification and control (primary or periodic) requires a good control system and calibration process. This paper focuses on the errors of measuring instruments in a dynamic system of metering fluids and respect of the tolerance defined by the international standards and recommendations. In a first step, we describe the experimental methodology adopted for evaluating the effectiveness of different systems Dynamic count. Next we will compare the results of measurements between the simulated values and the values read from the computer. Finally, we conclude on the validity of the instruments according to the errors identified and the errors.DOI: http://dx.doi.org/10.11591/ijpeds.v3i4.497

    The control and calibration of measuring instruments installed in dynamic metering station must have a good understanding of the evaluation and validation method of the error. This paper will address the calculation procedures for petroleum quantities. We discuss measurement, convert physical phenomena into electrical signals, control and permissible maximum errors of measurement instruments in metering systems of fluids. After, we compared the error of these instruments with the reference standards and recommendations

    The purpose of this paper is to review the essential definitions, roles and characteristics of communication on metering system. We discuss measurement, data acquisition and metrological control of a signal sensor from dynamic metering system. After that, we present instruments of sensor communication with more detailed discussions to the reference standards and the important fundamental parameters to consider when designing a dynamic communication metering system. We finished with control and calibration of turbine flow meter and we given resultats expermentaly of this work

    Co-digestion of vegetable peel with cow dung without external inoculum for biogas production: Experimental and a new modelling test in a batch mode

    This paper examined both experimental and a new modelling test for biogas production based on Co-Digestion Ratio (CDR) of vegetable peel (VP) with cow dung (CD) without external inoculum. For this, vegetable peel was used as a substrate and cow dung was used as a co-substrate. Reactors in triplicate were prepared. The vegetable peel concentrations were 12, 8, 6 and 4 g VS/l with the same cow dung concentration (4 g of VS/l) which corresponds to a CDR of 3:1, 2:1, 1.5:1 and 1:1. A new mathematical model corresponding to the biotech anaerobic digestion process based only on the (CDR) and (VS) was implemented under Matlab Simulink. The experimental results indicate that the optimal cumulative methane production (CMP) of 2000 ml was generated in the reactor containing a (CDR) of 3:1 which corresponds to a methane yield of 170 ml CH4/ g VS. i.e., an improvement between 23 and 26% comparing to all other CDRs. The experimental results were conformed by the new mathematical model. After applying the invented new idea by converting the constants (Rm, L and Gm) into functions (Rm =f1 (CDR), L=f2(CDR) and Gm = f3 (VS)) and relating them to each other using the Gompertz relation. The new model was able to predict the methane produced using only two inputs: VS and CDR. While in the literature studies, which were used Gompertz relationship for kinetic modelling, the constants must be recalculated each time as a new model, although the substrates used are the same, only the composition is different. Analysis of the variance (ANOVA) between the experimental and modelling results showed that there is no statistically significant difference, with a significance level of 0.05. Finally, the invented new idea can be a key to another different research that uses the same substrate
