Electrical Capacitance Tomography and Tomographic Flow Measurement















Welcome to the web site of Process Tomography Ltd. Please read an important news update by clicking here.

The easiest way to navigate this web site is by using the TABS (Home, News, Products etc.) at the top of each web page (including this one), or by using the links highlighted in blue. Most of the detailed information on this site is in .pdf format and requires a suitable reader to be installed on the viewing PC (eg Adobe Acrobat, which can be downloaded by clicking here if it is not already installed).

We specialise in the design and manufacture of a wide range of products for measuring very small values of electrical capacitance. These include Electrical Capacitance Tomography (ECT) systems, which allow the concentration distribution of dielectric materials (oils, plastics, minerals etc.) inside closed vessels to be viewed, measured and captured at high frame rates. Where the vessel walls are insulating, the measurements can be completely non-invasive. Our ECT systems cost from 25,000 for a basic single plane version to around 65,000 for a high-speed 2-phase flow measurement system. The exact cost will depend on the design complexity of the capacitance sensor design, the required data capture speed and whether flow measurement software is needed.

We also supply a unique instrument for detecting and locating faults in large electrical generator rotor windings and details of this equipment can be found at the website of our associate company Rowtest Ltd.

Details of our new TFL R5000 very high speed Electrical Capacitance Tomography and Flow Analysis system can be found here.

We can now supply a ranges of standard ECT sensors for use with liquids and granular solids and details of these sensors can now be found via the links on our products page.

For information about ECT and Process Tomography, please read About ECT and for information about our full range of measurement hardware and software, click here. You can read about current developments at PTL on our PTL Latest News page.

Most of the information on this web site can be viewed and downloaded directly by clicking on the Support Tab. For example, all of our product sales and applications literature is available online, together with some examples of applications of ECT technology. Recent additions include a comprehensive guide to the Fundamentals of ECT technology These documents can be viewed and downloaded in .pdf format from our Support page.

You will find a list of selected academic technical papers on ECT here, including a full list of papers at the last 5 biennial World Congress meetings on Industrial Process Tomography (WCIPT). We have also included a set of links to a number of related tomography research organisations here.

Information about the use of ECT in multiphase flow measurement can be found here and further information about ECT-based flow measurement products from our partner company Tomoflow Ltd. can be viewed and downloaded from our Download page.

Please contact us to request a quotation or for pricing information. We are a small highly-professional company and can respond quickly and flexibly to requests to supply modified or specialist equipment or to requests for consultancy work related to our innovative capacitance measurement technology.
