Description

Venturi cone is an innovative flowmeter which offers the ability to measure a differential pressure and a flow rate. Venturi cone offers better accuracy, variety of ranges, flexible installation, and requires less maintenance. The key benefit of venturi cone is the unique design, the ability to provide a repeatable accuracy up to 0.5 % of rate under the most harsh flow conditions. Furthermore, it offers a wide range of reynolds numbers. Venturi cone offers an exceptional sizing flexibility, such as diameter ½ ~ 120". Venturi cone assures a casting performance, with no moving parts to be replaced. Additionally, the contoured shape of the cone directs the flow without impacting the abrupt surface.

Specification

Accuracy	From ±0.5 % of actual flow (Certain fluids and reynolds number applications require special calibrations to achieve this value.)
Repeatability	±0.1 % or better
Flow ranges	10:1 and greater
Standard beta ratios	0.45 through 0.80, special betas available
Head loss	Varies with beta ratio and DP
Installation piping requirements	Typically 0 ~ 3 diameters upstream and 0 ~ 1 diameters downstream of the cone are required, depending on fittings valves in the adjacent pipeline
Materials of construction include	Duplex SS, 304SS or 316SS Hastelloy C-276 Carbon steels Special materials on request
Line sizes	0.5 ~ 120" or larger
End fittings	Flanged, threaded, hub or weld-end standard. Others on request
Configurations	Precision flow tube
