ERT Circular Sensors

Electrical Resistance Tomography Circular Sensors

ERT sensors comprise of multiple electrodes which must make electrical contact with the fluid within the process volume. The most common geometry is a circular sensor with the electrodes arranged uniformly around the circumference. This approach is suitable for pipeline based sensors for both R&D and industrial applications. Circular sensors can also be fitted to the circumference of process vessels although this tends to be limited to R&D applications. These sensors can be designed to minimise or eliminate any disturbance of the flow through the pipe by making the electrodes non-intrusive.

Laboratory Flow Loop

A typical laboratory sensor for low pressure and medium temperature applications would be of simple acrylic construction with electrodes fitted through the walls of the acrylic pipe as shown below. This type of construction allows for flow visualisation.

Integrated Tomography Rig

ITS is able to provide a full service tomography rig for mixing research. This can encompass any, or all of the following features:

gas injection points
Baffles
flat or rounded base
wall or baffle mounted linear sensor arrays
stacked circular sensor arrays
recirculation loop pipeline based arrays

The vessel can be fitted with top or bottom driven mixers and other sensor technology to meet user requirements.
