Improving The Accuracy Of Oilfield Multiphase Flowmeters By Understanding Flow Structure
Author(s): Andrew Hunt, Richard Foster Turner
Abstract/Introduction:
Measurement of multiphase flow in industrial applications remains an urgent need - oilfield flows, conveying , multiphase processes ... Customer requirements are tough - accurate , no in - situ calibration, independence of flow regime and variations in material properties ... ECT has the answers to some of these requirements - fast , non - intrusive, potentially low - cost and easily certified for hazardous areas, measures concentration, velocity and mass flowrate... - but low resolution , effects of structure shape and physical properties such as moisture Here we address ECT response in gas - liquid flows

An Integrated Flow And Pressure Metering Solution For Remote Locations Using The Water Industry Telemetry Standard Protocol Wits()
Author(s): Ray Keech
Abstract/Introduction:
In the water industry, telemetry system vendors developed proprietary protocols for communications between their field devices and master stations. ? Consequently end users of the telemetry system became locked in to the particular supplier. ? The Water Industry Telemetry Standards (WITS) group was created in 2003 to introduce change ? The first project undertaken was to produce an open standard for transferring data between field devices and a telemetry master station
