ABSTRACT:
A method for measuring average mass flow velocity in a duct employing an RTD (resistance temperature sensor or detector) sensing device which is a long, thin, unitary device adapted to be distributed across an extended field for the continuous, uninterrupted sensing or interrogation of such field. A very long, thin, ductile protective metal outer sheath houses a co-extensive body of insulation material, which in turn supports and electrically insulates one or more co-extensive RTD filaments and, in most forms of the invention, one or more heater filaments. The distributed RTD sensor may be configured in various ways to have continuous linear function sensitivity, continuous variable function sensitivity, or step function sensitivity. The distributed RTD sensor is used for measuring average mass flow velocity of fluids primarily in large ducts.
