New contributions and present limitations of the nuclear magnetic resonance velocimetry are illustrated by means of measurements in two plane symmetrical bifurcations, both with sharp apex and hips. The bifurcation angles were equal to 70 and 60 degrees and the area ratios to 2 and 0.83 in models 1 and 2 respectively. Velocity-induced phase-shift are encoded by bipolar magnetic field gradients. The velocity was measured in steady (Reynolds number $< 700$) and in non-zero mean starting-stopping (mean Reynolds number of 150, Stokes number of 30) laminar flows. The phantom experiments have demonstrated the following advantages of the NMR velocimetry: (i) the variations of the velocity components, in space (bend-like type motion in the branches...
