Key Benefits Include: - identify boundaries between gas/ liquid; liquid/ liquid; solid / liquid; liquid / foam; emulsion and water / organic phases... - measurements not dependent on hard interfaces, transparency or density differences - non-intrusive probes, able to scan through process fluid - Monitor soild suspension times ITS Solution A process tomography probe can be used to measure the depth of different components in a vessel in real time. The benefits of a tomography probe are that it can be left in the process fluid without disturbing process conditions and is then able to scan across a wide range of depths. In addition electrical tomography probes are extremely robust, able to withstand challenging temperatures, pressures, chemicals and (in the case of nuclear applications) high radiation fields. Data outputs can be processed and linked to selected process devices that can control mixing conditions and other parameters. The p2000 instrument using a linear probe is the suitable system for monitoring interfaces in aqueous systems.
