  • Orifice Flanged Union (AFM-OFU)

    The AFM-OFU Orifice Flanged Union is available in line sizes from ½” and larger, offering a versatile solution for differential pressure flow measurement in pipelines. It is designed to provide easy installation and maintenance while ensuring accurate flow readings.

  • Orifice Meter Plates (AFM-ORP)

    Our AFM-ORP Orifice Plates are available in sizes from ½” and above. These plates are precision-engineered for differential pressure measurement and are suitable for a wide range of fluids and gases. They provide a cost-effective, reliable solution for various flow measurement needs.

  • ASME Flow Nozzle (AFM-N)

    The AFM-N Flow Nozzle is an ASME-compliant, high-performance differential pressure flow measurement device. Known for its accuracy and reliability, this nozzle is ideal for applications that demand precise flow measurement, particularly in high-velocity and high-pressure environments.

  • Orifice Plate Meter Run (AFM-ORPMR)

    The AFM-ORPMR Orifice Plate Meter Run is specifically designed for measuring gas or liquid flows in pressurized piping systems. This "orifice meter tube" complies with ISO 5167, ASME MFC, and American Gas Association Report Number 3 specifications, ensuring it meets global standards for accuracy and consistency.

ASME Flow Nozzles:
Low and High Beta Ratios

ASME flow nozzles, including long radius nozzles, are available in two designs — low beta ratio and high beta ratio:

Versatile Use:
For beta values between 0.25 and 0.5, either design may be employed depending on the specific application needs.

High Beta Nozzles:
Suitable for diameter ratios between 0.45 and 0.80.

Low Beta Nozzles:
Recommended for diameter ratios between 0.20 and 0.50.

Venturi Nozzles for High-Velocity Fluids

Venturi nozzles are highly recommended for applications involving steam flow, high-velocity fluids, wet gases, and both clean and dirty liquids.
Key features include:

Rangeability:
4 to 1

Typical Accuracy:
1-2% of full range

Viscosity Effect:
