Integral V-Cone Flowmeter VD series

TRANSMITTER DIRECTLY MOUNTED! SIMPLE AND EASY INSTALLATION Integral V-Cone Flowmeter VD series OUTLINE VD series Integral V-Cone Flowmeter is a differential pressure type flowmeter. Unlikely to existing Orifice system, all necessary components for measuring flow rate of various fluids are combined and assembled for immediate start-up just by installing onto process piping and connecting with 2 core wiring. Connection and installation of bypass piping, 3 way valve and transmitter is not necessary. FEATURES Wide application V-Cone can measure almost all process fluids, i. e., liquids, slurries, gases and steam. Short straight runs By the unique flow restriction theory, the required straight runs both for upstream and downstream are much shorter than those for traditional orifice plates. Effective for space and cost saving for plant construction. Wide range ability V-Cone sensor offers 14:1 range ability which is much wider than orifice and Vortex flowmeters. Low permanent pressure loss The signal stability of V-Cone is more stable than that of orifice plates. Thus, the required P and per manent pressure loss are also much lower than orifice system. This saves total energy consumption in plants. Durable against wear and sticking V-Cone has "Self-Cleaning" capability because the fluid runs off from the beta edge of the Cone. Size availability 15mm (1/2") to mm (12") are ready to select to cover almost all possible line sizes. Easy installation and handling Bypass piping has been already done which saves installation and maintenance costs dramatically.

MEASURING PRINCIPLE The V-Cone is a differential pressure type flowmeter. Theories behind differential pressure type flowmeters have existed for over a century. The principal theory among these is Bernoulli's theorem for the conservation of energy in a closed pipe. This says that for a constant flow, the pressure in a pipe is inversely proportional to the square of the velocity in the pipe. Simply, the pressure decreases as the velocity increases. For instance, as the fluid approaches the V-Cone meter, it will have a pressure of P1. As the fluid velocity increases at the constricted area of the V-Cone, the pressure drops to P2, as shown here. Where Q = flowrate in actual cubic feet per second. k = constant that can change according to a particular flowmeter, dimensionless (see below for the equation for k for the V-Cone). Y = gas expansion factor, dimensionless.(y=1 for noncompressible applications) P = differential pressure in pounds per square foot. ρ = fluid density in pounds per cubic foot. Both P1 and P2 are measured at the V-Cone's taps and the difference is P : For the V-Cone : P = P1 P2 The P created b y V-Cone will increase and decrease exponentially with the flow velocity. As the constriction takes up more of the pipe cross-sectional area, more differential pressure will be created at the same flowrates. The ratio between the open pipe area and the open area at the largest cross-section of the cone is the Beta ratio. The equation for the Beta ratio of a V-Cone is : where D 2 d 2 D β = Beta ratio D = inside diameter of the pipe. d = outside diameter of the cone. If Q represents the flowrate, the equation of flow for a differential pressure type flowmeter is : Q ky P ρ k= π Cd 4 2Gc D2 2 1 4 where k = V-Cone meter constant, dimensionless. Gc = gravitational constant in feet per second squared. D = inside diameter of the pipe in feet. β = Beta ratio of the V-Cone, dimensionless. Cd = calibrated coefficient of discharge, dimensionless. Mass V-Cone flowmeter In measuring the saturated steam, we recommend to use VM deries with density compensation function built in. PTIONAL UNITS Panel instruments a. IR-6000 DIN48 48, Indication.
