1. a flow sensor apparatus (30) comprising:

  • Shell, it comprises inflow entrance (32) and flow export (32), shell is limited to the fluid passage (12) of extending between inflow entrance (32) and the flow export (32);

    Flow sensor (10) places in the shell and is exposed to fluid passage (12), and flow sensor (10) is configured to the relevant measured value of flow velocity of sensing and the fluid that flows through fluid passage (12) (28);

    AndUpstream porous embolus (22), it is positioned at the fluid passage (12) of the shell of flow sensor (10) upstream, its middle and upper reaches porous embolus (22) comprises polymeric material, wherein in flow sensor apparatus (30) operating period, fluid (28) flows through inflow entrance (32), pass upstream porous embolus (22), the flow sensor (10) of flowing through, flow through flow export (32) then, upstream porous embolus (22) is configured to fluid (28) the laminar flow section of enhanced flow through flow sensor (10).
