    Other Dp meters have centrally located openings and do not interact with this high velocity core. This is an important advantage to the V-Cone at lower flowrates. As the flowrate 3255 WEST STETSON AVENUE • HEMET, CALIFORNIA 92545 USA Printed In the U.S.A.

    The turndown of the V-Cone can reach far beyond traditional Dp meters. A typical turndown for a V-Cone is 10 to 1. Greater turndowns are attainable. Flows with Reynolds numbers as low as 8000 will produce a linear signal. Lower Reynolds number ranges are measurable and are repeatable by applying a curve fit to the measured Dp, derived from calibration over a specific Reynolds number range.

  • Page 7: Sizing

    Features Sizing The unique geometry of the V-Cone allows for a wide range of beta ratios. Standard beta ratios range from 0.45, 0.55, 0.65, 0.75, and 0.80. No Areas of Stagnation The “swept through” design of the cone does not allow for areas of stagnation where debris, condensation or particles from the fluid could accumulate.

    Each meter will produce a range of differential pressure and the transducer must cover that range e.g. a V-cone with a max. flow producing 230 inch water column would use a 250 inch or 300 inch DP transducer and would be spanned for 230 inches. The DP transducer must also be selected for the operating pressure and temperature of the metering application.

    Maintenance and maintain secondary and tertiary instrumentation according to the manufacturer’s instructions. Troubleshooting A V-Cone System On-Site This guide is intended to help you troubleshoot a V-Cone system. Keep several points in mind as you proceed: Trouble- Most V-Cones are calibrated devices. The meter has already had flow through it. If a cone is missing or a leak exists inside the meter, this would be discovered during the calibration.
