CAPACITIVE PROBE FOR GAS-LIQUID FLOW CARACTERIZATION

Nikolas Libert, Leonardo Lipinski, Marco José da Silva

Abstract

The correct measurement of gas-liquid two-phase flow is important in many industrial applications. In this paper, we describe the development and evaluation of a non-intrusive capacitive probe. Care was taken to allow for fast measurements (up to 5 kHz sampling rate). Two calibration procedures for void fraction measurement in annular and stratified flow are also described.
