Error source in flowmetering in cable-in-conduit conductors by time of flight.

Summary

Inaccuracies are caused by retardation of the heat pulse with respect to the flowing helium and by the progressive change in the shape of the pulse. The cause of these effects is the engulfing of cold metal by the heated slug of helium as it progresses downstream. Because the magnitude of these effects depends on the specific heat of the metal, the error in the velocity is small for low temperatures but rises rapidly with increasing temperature.
