This paper describes the development of a dual plane Electrical Impedance Tomography (EIT) system that is capable of acquiring data at frame rates of around 1000 dual-frames per second (dfps) providing both magnitude and phase information. The principles of the hardware operation are discussed and the operation of the control software is described. Five separate experimental setups ranging from a simple rising bubbles test to a oscillatory baffled reactor and flow velocity profiles demonstrate that fast acquisition rates provide essential information in some type of applications.
