Abstract
A flowmeter has an elongated housing with a fluid inlet, a fluid outlet and an axial passage therebetween. The fluid passage contains a flow splitter section and is connected to a flow sensor assembly. The flow splitter section is formed by a surface defining a longitudinal fluid path and a flow splitter secured in the fluid path, so as to form an annular gap between the surface of the fluid path and the flow splitter. The surface of the fluid path defines a tapered calibration bore. The flow splitter has a tapered calibration section comprising the upstream portion of the flow splitter and at least one tapered expansion section comprising the downstream portion of the flow splitter. The taper of the calibration section is substantially parallel to the taper of the calibration bore, and the taper of the expansion section diverges away from the taper of the calibration bore.
