ABSTRACT:
A sensor for a hydro resistance anemometer is designed for immersion in a flowing fluid to provide flow velocity information. The sensor is of a cylindrical configuration with a hemispherical nose. A driving electrode extends axially along the sensor and is exposed to the flowing fluid only at the center of the hemispherical surface of the sensor nose. A reference electrode of annular cylindrical configuration is disposed coaxially about the driving electrode and separated therefrom by a dielectric insulating material. The power dissipated through the sensor is typically on the order of only ten milliwatts.
