McCrometer V-Cone DP flow meter

Click2Contact

McCrometer’s V-Cone flow meter is claimed to be inherently more accurate than traditional DP instruments because of the flow conditioning function built into its sensor design. Its centrally located cone interacts with the fluid steam, reshaping the velocity profile to provide a stable signal that increases measurement accuracy.

The pressure difference exhibited between the static line pressure and the low pressure created downstream of the cone is measured via two pressure-sensing taps, one placed slightly upstream of the cone and the other located in the downstream face of the cone itself. The pressure difference is then incorporated into a derivation of the Bernoulli equation to determine the fluid flow rate.

The V-Cone flow meter is available in line sizes from 1.25 to >300 cm in materials and with flanges compatible with any application. It operates over a wide flow range of 10:1, is accurate to ±0.5% and offers repeatability to ±0.1%. It features standard beta ratios of 0.45 to 0.85 with custom betas available. It is constructed of rugged duplex 2205, 304 or 316 stainless steel, Hastelloy C-276, 254, SMO and carbon steels with special materials and testing available on request.

With built-in flow conditioning, the V-Cone flow meter nearly eliminates the up- and downstream straight pipe runs required by other DP instruments, such as orifice plates and Venturi tubes. Requiring only 0-3 straight pipe diameters upstream and 0-1 downstream for precise operation, it reduces typical straight run by 70% or more as compared to traditional flow measurement technologies.
