Fluid flow controller and meter |
摘要 |
A fluid flow controller and meter including a metering tube with a bore formed axially therein having a slit-like orifice axially disposed and intersecting the bore along the length thereof. Flow through the meter is controlled by a valve member which moves in the passage of the metering tube and across the slit-like orifice. In a preferred embodiment, the slit-like orifice is in fluid communication with a site tube which contains a flow sensitive element which is responsive to the flow induced. The slit-like orifice achieves a linear flow response to changes in the relative position of the valve member.
