Flow rate detection mechanism with a restriction element for mass flow meters

Image Number 7 for United States Patent #6247495.

A flow proportioning assembly for dividing a portion of a fluid flow such as gas for presentation to a sensor includes a holder member having a central opening and forming an exterior peripheral passageway when inserted within a conduit of a flow meter housing. A resistor member can be adjustably mounted in the central opening downstream of a holder member aperture to encourage a laminar flow pattern and a large entrance port and a large exit port can communicate with a passageway that is operatively connected with a sensor. The exit port is downstream of the resistor member. Flexible fastener members can engage the resistor member and the holder member for ease of mounting. The resistor member can also comprise a helical arrangement of small fluid passageways to encourage laminar flow.
