Weighing without touching

Andy Hunt presented an overview of electrical capacitance tomography to an audience of 30 on June 5th at the Forest Lodge Hotel, Lyndhurst, Hampshire. The seminar, entitled Weighing Without Touching, was one of a series of evening events that are offered by the Wessex Section of the Institute of Measurement and Control. These evenings provide a relaxed setting for learning, socialising, and networking.

Andy Hunt has spent 30 years working on flowmeters for multiphase flow including dry solids, wet steam and three-phase oilfield flows. In the last few years electrical capacitance tomography (ECT) has been developed from a research idea to a non-intrusive, fast way of measuring the distribution and mass flow rate of product in a process pipe or vessel. These meters can measure the mass of product flowing with no contact and no obstruction.
