Abstract
Measuring of mixed phased flows to determine flow regime through the use of circumferentially shifted electric fields and measurement of resultant diametral and chord conductances with certain combinations of ratios of diametral to cord conductances serving as a signature of flow regime.
Claims4
Method of determining phase cross-section distribution of mixed phase fluids comprising,
- establishing a cyclically rotating pattern of substantially limited, to less than full cross section, diametral and chord voltage fields and measuring the diametral and chord conductances under said voltage fields,
- establishing ratios of essentially simultaneous diametral and chord conductances,
- providing a signal based on said ratios.
Apparatus for determining phase cross-section distribution of mixed phase fluids comprising,
- a conduit,
- electrodes arranged in a cross-section of said conduit in a peripheral array,
- means for rotatably establishing different arrays of oppositely poled electrodes,
- means for measuring diametral and chord conductances, taking the ratio thereof in different combinations and providing a useful signal therefrom.
