The functional diagram of a noncontact pulse control of 
fluid velocity without undocking of a pipeline and the main characteristics 
of the control with simultaneous counteremission of an ultrasound 
by superposed transducers with a decreased (by damping sound ducts) 
echo-pulse reverberation are considered.
