A careful measurement of the relevant two-phase flow parameters is the basis for the understanding of many thermohydraulic processes. Reliab le two-phase instrumentation is therefore essential for the connection between analysis and experiment especially in the nuclear safety rese arch where accident scenarios have to be simulated in experimental fac ilities and predicted by complex computer code systems. Ambitious deve lopment programs have been carried out in many institutions and countr ies to improve two-phase instrumentation. Advantages as well as limita tions of some of these systems are discussed in this paper. In the las t 10 to 15 years substantial progress has been made, although there ar e still goals for further developments. And it is still a fact that in many cases measured data taken from large experimental facilities can not be compared directly to the parameters calculated by the codes. Ca reful comparison and interpretation of both calculated and measured re sults by experienced researchers will continue to be the key for therm ohydraulic understanding of complex two-phase phenomena in the future.
