Abstract
A body (12) containing a substantially cylindrical bore (14) as fluidly connected in a straight pipe run, the bore having opposed relatively upper and relatively lower wall portions (94,96) and opposed side wall portions. A pair of substantially solid wedge members (30,32) are detachably secured to the side wall portions and project toward the bore axis (34), partially blocking the flow of fluid through the bore to produce a differential pressure upstream and downstream of the wedge members. Sensors (64,66,68,70) are provided upstream and downstream of the wedge members, through the side walls of the bore, to obtain differential pressure measurements from which the fluid flow rate can be computed.
