Analysis of Conductance Probes for Two-Phase Flow and Holdup Applications [PDF]

open access: yesSensors, 2020
In this paper we perform an analysis of the conductance probes used in two-phase flow applications especially for two-phase flow tomography of annular flow, to measure the waves produced in the interface with different boundary conditions without perturbing the flow, and in addition we examine the holdup applications as measuring the average void ...
