ERT Linear 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 flush with the wall.

Linear ERT sensors were developed as a more industrial deployable configuration. The electrode array is mounted on a probe which is typically inserted into a process vessel through a nozzle or port.

Laboratory-scale sensors

These are typically manufactured from 18 mm diameter PTFE rod and the sensing length can be designed to make them suitable for insertion into vessels ranging in volume from approximately 1 to 10 litre. They are compatible with standard glass fittings.

Pilot-scale sensors

They are made from large diameter PTFE rod which can be re-enforced with a metal internal if required. These are designed specifically for customer's vessels with appropriate flange arrangement to fit the available nozzle and maintain pressure integrity of the vessel.
