Using Coriolis Mass Flowmeter for Wet Gas Metering

Evolution of Wet Gas Venturi Metering and Wet Gas Correction Algorithms

The Venturi meter is a straightforward pipeline device used for the metering of gas and liquids. This article presents a brief summary of the creation and characterisation of the modern Venturi meter, including the historic development of public domain algorithms to derive two phase (gas and liquid) flow rates from differential pressure measurements. The use of Venturi meters in multiphase oil ...

Mass Flowmeter Using a Multi-sensor Chip

We report here a novel two-mode mass flowmeter that can be operated in either thermal or differential pressure mode. By combining these two complementary operating principles, the performance can be improved significantly. This flowmeter is based on a multi-sensor chip that includes a 1-D array of shear stress, pressure and temperature sensors. The multi-sensor chip can also be employed in many...

Fault Detection System in Gas Metering Station Using Neural Network

This research study focuses on the discussion regarding the development of fault detection in gas metering station using an Artificial Neural Network (ANN). The proposed model of fault detection applies ANN approach in order to provide a good detection method for billing purpose. However, one of the main problems faced by gas metering system is the undiagnosed faulty condition of measurement. M...

Correcting a Coriolis Meter for Two Phase Oil & Gas Flow

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...
