A technique for measuring the fluid velocity in a two-phase 
flow using a combination of the electrochemical method and the conduction 
method is described. The point of this technique is numerical analysis 
of complete realizations of signals from the electrodiffusion velocity 
transducer. The dependence of the results of measurements of local 
hydrodynamic characteristics of the bubble flow on the level of gas-phase 
cutting out has been investigated. The measurement data for the local 
gas content, the fluid velocity, and the velocity pulsations during 
bubble mixture motion in a tilted channel are presented.
