Electrical Tomography (ET) is an imaging non-nuclear imaging technique used to determine the permittivity distribution of dielectric media within the region of interest. The technology enables real-time imaging and measurement of media inside process pipes and separator tanks. The technology works well in processes with multiphase flows, including for example oil, water, gas and solids.
Process imaging and monitoring is based on the permittivity/conductivity distribution of the media.
Measurement Principle - Electrical Tomography (ET)
Voltage is injected between electrodes of the tomographic sensor installed into a process pipe or tank. As a result, measured currents are sent to the electrical unit. This enables calculations that form the process image and trends.
Examples of Permittivities and Conductivities
|Water / humidity||80.4|
|Medium||Conductivity, σ (S/m)|
|Drinking water||5.00×10−4 to 5.00×10−2|
|Air||3×10−15 to 8×10−15|
See our products to find out how we apply ET technology to industrial processes.
