Wire-mesh sensors are flow imaging devices and allow for high spatial and high temporal resolution visualization of phase fraction (e.g. gas void fraction or liquid holdup) distribution of multiphase flow. This type of sensor has been successfully employed to investigate a number of single phase and two-phase flow phenomena in the past. In this contribution, an overview about the operation principle of wire-mesh sensors along with the signal and image processing procedures to obtain physical flow parameters from the electrical measured signals is given. Besides describing the state of the art of wire-mesh sensor technology, the latest development of a temperature wire-mesh sensor is depicted in detail.
