| Abstract: | A new type differential product-internal venturi tube is introduced, which concentrates metrological advantages of classical venturi, annular orifice and wear-resistant orifice plates. The design, principle of operation, specification and applicability of this differential product are outlined. The method for determining the expansibility factor and the mechanism of forming the excellent metrological performance for this differential product are also described. The prospect of replacing the traditional differential products (e.g.orifice plates) with this new device is expected. |
