•First effort to discuss the simultaneous measurement of multiple physical variables in single-phase and multiphase flow.•Both intrusive and nonintrusive techniques for coupled measurement are illustrated and commented.•The most basic measurement of coupled velocity and temperature are discussed in very detail.•Very recent progress on the multi-parametric measurement is also presented.•Machine learning is a promising means for the reconstruction of flow field and estimation of high-quality data. Multi-parameter simultaneous measurement is one of important requirements for multiphase flow studies, since there are many physical and morphological parameters of interest both for fundamental and industrial applications, including velocity, temperature, concentration, pressure, free surface fluctuation, bubble or particle dynamics, etc. Techniques for single phase flow or for single-parameter measurement has long been developed. However, though measurement techniques for simultaneous multiple parameters already had many options to choose, there is still a high need for coupled measurement skills with high precision, high temporal and spatial resolutions, and high robustness. Moreover, from large scale thermal flow to microscaled flow with heat transfer, requirement and accessibility for measurement tools vary largely. This work aims to present a comprehensive review on the fundamental and recent advances of multi-parameter simultaneous measurement techniques for multiphase flows, and of course with the key concept and application for single phase flow as a premise knowledge. Part A of this review will focus on the simultaneous measurement techniques of velocity and temperature / pressure. The factors influencing the uncertainty and resolution are also discussed, along with the typical applications of each multi-parameter simultaneous measurement technique. Then conclusion for the coupled measurement of velocity and temperature / pressure and remarks on the future techniques are presented. In serial part B of this review, further information of simultaneous measurement methods involving phase characteristics will be specially discussed and commented.
