ABSTRACT:
The apparatus (10) includes a metering tube (18) and a sight tube (22) intersecting the metering tube (18). Fluid communication between a bore (68) formed axially in the sight tube (22) and a passage (38) in the metering tube (18) is provided through an orifice (64). Flow through the meter (10) is regulated by a valve member (40) which moves in passage (38) and across the orifice (64). The bore (68) in the sight tube (22) is tapered upwardly and outwardly, and a flow sensitive element (72) rises and lowers within the bore, depending upon the flow induced. As the element (72) rises, an annular space (86) defined between the inner wall of the bore (68) and the determinant diameter (74) of the flow sensitive element (72) increases to define an annulus having a greater area than when the flow sensitive element (72) is in a lower position.
