Abstract
Apparatus for measuring the rate of fluid flow through a conduit including a flow rate sensor assembly connected to suitable electrical circuitry and indicating instrumentation. The sensor assembly includes a heated wound resistive element which senses fluid flow rate and a fluid temperature compensating wound resistive element, both elements being mounted on a common spherically shaped surface which is exposed to the flow media.
Claims8
Flow sensing apparatus comprising support means adapted to be mounted on a fluid conduit and having a convex spherically shaped support surface exposed to the fluid in said conduit, a first resistive element spirally wound on the central section of said surface for sensing the flow rate of the fluid, a second resistive element spirally wound on the outer section of said surface for compensating for ambient temperature conditions of the fluid, both of said elements being directly exposed to the fluid, and electrical circuit means for producing an output control signal in response to the resistive condition of said elements.
Flow sensing apparatus comprising support means adapted to be mounted on a fluid conduit and having a substantially spherical convex surface exposed to the fluid in the circuit, said surface having a spiral groove formed therein, electrical sensing means including a first resistive flow rate sensing winding wound in the inner turns of said groove adjacent the center portion of said surface, and a second resistive fluid temeperature compensating winding wound in the outer turns of said groove, said windings being directly exposed to the fluid in said conduit.
