10.09 V-Cone®, An Alternative to Orifice Meter in Wet Gas Applications - Stephen A. Ifft - This paper will discuss the use of the V-Cone differential pressure flowmeter to measure the flow of wet gas. Wet gas flow measurement is gaining considerable attention due to its importance in the oil and gas industry. Separator and well-head flow lines are two examples where wet gas can occur in a production system. Orifice plates have long been used for these applications. While orifice plates offer good measurement in clean gas applications, an alternative is needed that will provide better performance in the harsh environment of wet gas flow.

10.09 Partially Closed Valve Effects on the V-Cone Flowmeter - Stephen A. Ifft - Research conducted indicates that the V-Cone flowmeter is less susceptible to upstream flow disturbances than traditional flowmeters. This  testing has placed various flow disturbances upstream of the V-Cone including single elbows, double elbows out-of-plane, valves, and swirl generators. In an effort to further quantify the effects of partially closed valves on the V-Cone, McCrometer has completed the first in a series of valve installation effects tests.

10.09 Permanent Pressure Loss Comparison Among Various Flowmeter Technologies - Stephen A. Ifft - This paper explores the issue of permanent pressure loss through various types of flow metering technologies. Of particular interest is the V-Cone. The V-Cone flowmeter is a differential pressure device produced by McCrometer, Hemet, California, USA. By design, the V-Cone measures differential pressure created by a cone positioned in the center of the pipe. The open area through which the fluid passes is stretched over the edge of the cone. This annular space appears to constrict flow dramatically compared to other metering technologies. This paper compares the permanent pressure loss among meters in a typical application.

These tests have shown how the V-Cone meter responds to different amounts of liquid entrained in a gas flow and have enabled correction factors to be developed.

Case Notes

10.09 Don’t Let Valves Come Between You and Accurate Flow Measurement - Jim Panek -  Getting valves and flow meters to work together is sometimes a challenging task within industrial water and wastewater applications. Valves tend to create the kind of irregular media flow patterns in pipelines that make it a real challenge to achieve accurate flow measurement of liquids, gas or steam. That’s why many types of popular liquid flow meters require straight pipe runs. Unfortunately, the nature of the process or the kind of space required for long straight runs of pipe is often an impossible luxury in many of today’s plants.

10.09 Flow Meter Research for APS Beam-Lines - Jeff T. Collins & Brian Batzka - Many critical APS beam-line components, such as the photon shutters and fixed masks, utilise porous media for heat transfer enhancement and consequently rely on steady operation at design flow rates to ensure that the proper levels of heat transfer enhancement are maintained. it is therefore necessary to ensure that the flow metering system, which the component is interlocked on, has a high degree of reliability.

10.09 Flowmeter Smoothes City's Troubled Waters - An application note for the water industry.

10.09 V-Cone Coke Oven Gas Case Study - Flow monitoring of coke-oven gas is difficult due to solids build up on interior surfaces. Heavy accumulation often renders venturis, orifice and segmental orifice plates incapable of accurate flow measurement. In addition, the pressure-sensing ports of venturi or orifice plate flowmeters become plugged, making the readings of these primary differential pressure devices difficult, if not impossible.

The technical paper describes the reasons why the Paper Plant considered the replacement of a flow meter on the steam outlet of a Recovery Boiler.

10.09 Use of V-Cone Fuel Flow Meter to Measure Coke Oven Gas & Natural Gas Flow in a Combined Heat and Power Plant - Ann McIver and Dr. R.J.W. Peters - This paper describes key aspects of the Citizens Thermal Energy district energy system in Indianapolis. It will present the requirements imposed, through the continuous emissions monitoring rules established by the Environmental Protection Agency (EPA), as delineated in 40 CFR 75. The reason for the choice of the V-Cone, which is not a fuel flow metering technology specifically addressed in the regulations, will be presented and the tests required by the EPA to enable the V-Cone to be accepted. The results of the flow tests in an independent laboratory before and after a period in service will be given.
