Clamp-on Ultrasonic Flow Measurement of Natural and Process Gases


FLEXIM‘s ultrasonic gas flow meters use the proven clamp-on transit-time correlation technique also employed for the F series liquid meters. Special ultrasonic transducers are simply clamped onto the outside of the pipe and never come in contact with the gas.

FLUXUS® G represents the ideal solution for non-invasive gas flow measurement. FLEXIM’s non-invasive technology is an advantageous and cost-effective alternative to conventional methods, particularly with chemically aggressive, poisonous or high pressure media. With their extremely wide turn-down ratios, the instruments of the FLUXUS® G series register even the smallest flows.

Non-invasive Measurement

  • No contact with the medium, therefore no possibility of chemical attack. No need for expensive special materials (sour gas applications for example)
  • No wear and tear, even with high flow velocities or with gas containing particles
  • No clogging of small bore impulse lines with deposits, condensate, inhibitors, oil vapors, dust (as happens when using impulse lines in the measuring system)
  • Insensitive to dust and humidity

Plant-wide Condition Monitoring

In addition to the most important assets found in industrial facilities, there are often a host of “supporting” assets that make up the balance of the plant such as pumps, motors, blowers, heat exchangers, fans, and others. This auxiliary or plant-wide equipment may be spared or sacrificed, and its impact on the process stream may vary from moderate to minor. Regardless, such machines—just like their more highly important counterparts—can benefit from Condition Monitoring. Condition Monitoring provides affordable, effective portable and permanent condition monitoring solutions that are delivering tangible benefits for tens of thousands of customers around the globe.

Financial Justification

For many assets, failure can mean substantial or total loss of production, often worth millions per day. Or it can lead to the release of hazardous substances, fires, and even explosions— resulting in a severe safety hazard as well as fines for violating environmental regulations.

Maintenance Costs

When viewed on a per-asset basis, maintenance costs for plant-wide assets can appear modest. However, when viewed collectively across the dozens, hundreds, or even thousands of assets in a typical plant, these costs can be appreciable. Reducing the maintenance costs on each asset through effective condition monitoring—even by a mere 10%—has a large impact on plant profitability. Condition Monitoring is a planning tool that allows more effective insight in planning and asset management, allowing maintenance to be done in advance of a functional failure.

Things to think about as you move towards Predictive Maintenance:
  • 90% of failures are NOT time-based.
  • 50% of companies site maintenance and reliability as a top priority.
  • It costs 6x as much for unplanned events vs. planned maintenance in process industries.
  • A 60% estimated increase in environmental, health and safety spending among global exploration & production companies.
  • 50% of workforce to retire in the next 5 to 10 years. Knowledge & experience is not being transferred.
Potential impact of a conditioning monitoring program and the move towards Predictive Maintenance:
  • -70% Machinery breakdowns 
  • -40% Plant downtime
  • -50% Maintenance costs
  • +25% Production
