A series of two-phase, air-water tests performed in vertical upflow with advanced spool piece I and with conductivity proves obtained from Atomic Energy of Canada, Ltd. (AECL), is described. The behavior of the three-beam densitometer, turbine meter, and drag flowmeter is discussed in terms of two-phase models. Application of some two-phase mass flow models to the recorded spool piece data is made and preliminary results are shown. Velocity and void fraction information derived from the conductivity probes is presented and compared to velocities and void fractions obtained using the spool piece instrumentation. Preliminary results obtained with a vortex shedding meter in air-water, two-phase downflow are presented.
