Power Generation

Meters and materials to meet each power generation client’s specific needs


For nearly three decades, we have provided the power generation industry—conventional and nuclear—with a range of flow measurement equipment to give each client the optimum solution for each application. With a variety of types and numerous choices of materials, all our meters share two key characteristics: high accuracy and high reliability.


Classical Venturi PFS-CV (line size from 1.0” through 180”)
This meter is designed to measure full pipe clean gasses, or liquids over various temperature and/or pressure ranges, especially for high temperature and high pressure steam or water associated with power generation. We manufacture in accordance with the applicable ASME and/or Fluid Meters, 6th Edition, codes and practices.


Features:

  • High accuracy and reliability
  • Low permanent pressure loss
  • Produced in accordance with ASME-MFC-3M-l989
  • Custom designed for specific applications


Halmi Venturi HVT-FV (line size from 1.0” through 180”)
The HVT-FV is designed to measure full pipe clean gasses, or liquids over various temperature and/or pressure ranges, especially for high temperature and high pressure steam or water associated with power generation. We offer this design as a fully fabricated element with a broad range of materials, beta ratio(s) and end treatments (flanged, mechanical, beveled for in-line welding) or any other configuration the application requires.


Features:

  • High accuracy and reliability
  • Low permanent pressure loss
  • Low installed cost
  • Long service life (up to 15 year warranty)
  • Unaffected by downstream piping
  • Custom designed for specific application
  • Field verifiable


ASME flow nozzles PFS-FN (line sizes from 2” through 25”)
We manufactured these nozzles in accordance with ASME MFC-3M-2004 in 300-series stainless steel for most applications due to the high velocities and extreme environments to which they are exposed. Other materials are available for extreme temperatures and corrosive service.


Features:

  • ASME Section 1
  • ASME B1.1-Power piping
  • ASME B1.3-Process piping


ASME flow nozzle PTC-6 (line sizes from 4” through 24”)
These nozzles meet the ASME PTC-6 1996, Performance Test Code for Steam Turbines requirements and are intended to be the primary flow measurement device for steam turbine acceptance testing. Test sections consist of a low-beta series ASME throat-tap flow nozzle that is installed in a section of pipe approximately 30 diameters long. The upstream section of pipe, which is approximately 20 diameters long, is carefully honed on the inside to insure cylindricality/finish for a minimum of four pipe diameters upstream of the nozzle. The downstream section of pipe is approximately 10 pipe diameters long. A flow conditioner is built into the upstream pipe section at a distance of approximately 16 pipe diameters upstream of the flow nozzle.


Design standards:
All our primary PTC-6 flow sections are designed in accordance with the applicable sections of the following standards.

  • ASME PTC-6 1996
  • ASME PTC 19.5
  • ASME Research Committee Report on Fluid Meters-6th.Edition


Fabrication standards:

  • ASME Section I
  • ASME B31.l-Power piping
  • ASME B31.3-Process piping
