Flow Nozzle

Product Summary

The Flow Nozzle is a pressure differential flow measurement instrument, known for its aerodynamic design that results in lower line loss and reduces residue accumulation in the orifice. This instrument is particularly suitable for steam measurement, where the process velocity is high. Its unique features make it an exceptional choice for applications where efficiency and precision are essential.

Main Features:

  • Versatility in Applications: Applicable in lines with high velocities or in the presence of abrasive materials.
  • Reduction of Permanent Pressure Loss: Minimizes fluid resistance, improving system performance.
  • Ideal for Steam Measurement: Due to its ability to handle high process speeds.
  • Aerodynamic Profile: Reduces instrument wear, extending its lifespan.

Operation: The Flow Nozzle consists of a nozzle designed according to established standards, where the instrument's body is centrally positioned perpendicular to the pipe axis. This configuration alters the fluid flow profile, generating a pressure differential that is measured and interpreted to represent the process flow. The operating principle is based on the continuity and Bernoulli's equations.
