    BIF Universal Venturi Tube

    BIF Universal Venturi Tube is a high-accuracy, precision-manufactured flow meter designed for the most arduous of process conditions. The patented UVT hydraulic shape provides a low noise and repeatable high-accuracy flow signal for the most difficult flow meter applications. Through an exclusive sales agreement, Curtiss-Wright is the sole commercial nuclear sales channel for the full portfolio of BIF products.

    Key Features and Benefits

    • Accuracies of ±0.25% of actual flow are achievable in line sizes 2” to 48”
    • End connections are matched to the needs of the existing process system or new process system requirements
    • Flexible numbers of high and low pressure tap sets from one to six sets
    • NIST traceable flow laboratory calibration available

    General Specifications

    • Sizes: 2” to 48” diameter
    • ANSI Pressure Class: 150 to 2500
    • End Connections: Flanged, Screwed, Socket Weld or Butt Weld
    • Quality Class: Commercial, Safety-Related, or ASME Code, Class 1, 2, 3
    • Materials: Stainless Steel, Carbon Steel, Bronze or Copper Alloys; Special materials such as Monel or Inconel

    Principles of Operation

    The Venturi measures flow by creating an area of higher velocity in the throat of the device. This higher velocity comes at a decrease in the potential energy of the process fluid that can be measured as a lower pressure. Thus the difference in pressure between the inlet of the Venturi (pipe diameter) and the throat of the Venturi is proportional to the flow of the process fluid. With no moving parts and no replaceable parts, the BIF Universal Venturi Tube is designed for lifespans of greater than 60 years.
