Abstract
The flow rate is determined from the heat transferred from an electrically heated wire stretched in a fluid flow to the fluid. The wire is placed not on a plane normal to the flow but within a section of the fluid passage bounded by two spaced planes normal to the flow. Preferably the wire is composed of series of line segments which are distributed evenly not only around the central axis of the passage but also in the direction of the flow so that the heat release from the wire in its entirety corresponds to the mean value of fluid velocities at various points.
