This paper introduces the composition and working principle of field service gas flow standard device based on meter. Through analysis uncertainty verification measurement results, it is confirmed that meter method can be applied to flowmeter.

It is also common for flowmeters to be installed downstream of a two or three phase separator. If the well conditions change or the separator has been incorrectly sized, then it is possible that the oil liquid outlet may have some gas carry under. The effects of gas entrainment on the output of ultrasonic and Coriolis meters has been reported previously [1] [2]. It is already known that gas ent...

This paper presents a novel stationary phase for silicon microfabricated columns for gas chromatographic (GC) separation of light alkanes. Coated columns show an excellent efficiency, up to 8000 theoretical plates per meter and enable complete separation of light isomeric alkanes. An optimized column, with a thicker deposition, even enables the fast separation of a natural gas like mixture of l...

Several transmission and distribution companies in Western Europe operate test facilities for testing industrial meters like larger diaphragm gas meters, rotary gas meters and turbine gas meters. Alternatively, they lease mobile provers. Those installations are not suitable to perform the initial calibration (and try to save money on the calibration costs), but are suitable to perform all kind ...

Annular gas-liquid two phase flow is widely encountered in the nuclear industry. Various combinations of techniques have been employed in annular gas-liquid two phase flows to measure the flow parameters (e.g. liquid film thickness, gas volume fraction and the phase flow rates). One of the most useful techniques which has proven attractive for many multiphase flow applications is the electrical...

in recent decades energy sector has been most important division in sociopolitical national and international dialogs. policy making in energy sector in iran is a strategic subject because of independency of our national revenue to oil & gas export in one way and huge oil & gas reservoirs in iran (137 billion barrel in oil and 28.3 million cubic meter in gas) in other hand. this paper investiga...

Large IT systems are often acquired in a tender process where the customer states the system requirements, a number of suppliers submit their proposals, and the customer selects one of them. Usually the supplier uses an existing system as basis for his proposal. He adapts it more or less to the customer's requirements. This paper is a study of a specific tender process. The customer was a Danis...
