ABSTRACT:
In a borehole logging tool, a hot wire or hot film anemometer measures fluid flow entering or exiting the borehole at the wall of the borehole. The logging tool has open sensing pads mounted on the arms to place the sensor pads at the wall. The sensor pads are open to fluid flow to provide minimum disruption of flow. Other sensors measure flow direction, capacitance, and temperature.
