Abstract
An eccentric, smoothly tapered body for installation into cylindrical pipe to cause a constriction in the pipe to facilitate measuring the flow of fluid through the pipe. The body defines a flow constrictor having a smoothly tapered inner surface having a leading edge and a trailing edge and an apex therebetween. A bore extends through the flow constrictor at the apex. Pressure is measured at the bore at the apex and upstream of the flow constrictor and flow rate is calculated from the pressure differential therebetween.
