A doublet splitting of the squashing mode in He3 — В which has been observed recently is connected with the existence of superflow. We estimate the value of this effect within Brusov-Nasten'ka-Kleinert theory. The possibility of using the collective mode splitting as a measure of superfluid velocity is discussed.
