The calibration and use of a shielded dual sensor hot-wire probe, originally developed at McGill University for velocity measurement in highly turbulent and reversing flows, is described. The new probe permits measurements to be made in flow conditions which are not amenable to conventional hot-wire techniques. Two conventional hot-wire anemometers are used to drive the probeand a simple electronic circuit is required to decode the signals and producea continuous voltage analogue of the velocity component in one dimension.
