Conductance Sensors - case studies
Electrical conductivity is the ability of a material to build an electric current in the presence of an electric field. Metals are good conductors and therefore exhibit a large conductivity. Insulators are bad conductors having a very small, close-to-zero conductivity. In liquids, particularly aqueous solutions, the conductivity is greatly affected by the amount of dissolved charged atoms or molecules (ions).
Conductivity measurements are widely used in industrial and environmental applications as a simple and inexpensive way to control the ionic content in a solution. In water purification systems, the conductivity is monitored at different stages of the process. Since the mobility of the dissolved ions is affected by temperature, these monitoring systems are required to either control the process temperature or to compensate readings according to the sample temperature.
PUC-Rio - Fluids Engineering Laboratory (LEF)
The Fluids Engineering Laboratory (LEF) at the Mechanical Engineering Department of PUC-Rio conducts both fundamental and applied studies in the fields of fluid mechanics and heat and mass transfer.
The Nexus R200 conductance is being applied in two-flow experimental investigations, enabling high-speed flow monitoring data for gas fraction and water cut overtime.

NUEM - Multiphase Flow Research Group
NUEM is the Multiphase Flow Research Center of the Federal University of Technology – Paraná. It conducts research fundamental and applied research, both theoretical and experimental, involving multiphase flow in pipelines and equipment.
The Nexus R200 conductance was evaluated using two-wires electrodes to experimentally investigate and characterize two-phase flow in an experimental loop 35 meters horizontal long / 14m vertical height.
