Clamp-on Gas: High-precision and
non-contact gas flow measurement
deltawaveCoG
Simple and safe: Ultrasonic flow meter for gas using clamp-on technology
Precise and comprehensive data acquisition
To ensure accurate and comprehensive data acquisition, deltawaveCoG is also an integrative volume corrector, providing a variety of values including flow rate, volume, standard flow and total mass, among others. It also harmonizes the compensation and acquisition of pressure and temperature values via analog inputs and PT100.

Reliable and user-friendly: the ultrasound gas flow meter deltawaveCoG
The technology of ultrasonic gas flow meters is thoroughly incorporated in the deltawaveCoG, which is not only a reliable ultrasonic gas flow meter, but in addition is suitable for a variety of application scenarios. With a clear graphical display and accelerated setup options, the flow meter for (natural) gas deltawaveCoG can be parameterized in a remarkably short time, guided by the integrated on-screen help. The auto-optimizer optimally adapts the measurement parameters to your line. And the robust mounting kit allows for quick and stable installation of the transducers.
Transducers have never been mounted so fast!
Advantages of deltawaveClamp-on-Gas (deltawaveCoG) at a glance
- 100% Contact-free with the medium
- 100% Wear-free
- 100% Leakage proof
- 100% Hygienic
- 100% Pressure loss free
Safe in hazardous areas
Navigating in hazardous areas, deltawaveCoG guarantees maximum safety in the application, as both the electronics (Eex-d or Eex-n) and the clamp-on transducers (Ex-q) are Ex-approved. This opens the way for optimal safety, allowing the combination of Ex and non-Ex components as required, effectively saving money without compromising safety.
For example, if only a small radius around the pipeline is in the hazardous area, you can place the non-Ex electronics outside the hazardous area. Simply order the ultrasonic transducers in the Ex version. Your benefit: lower costs without compromising safety.
Applications for clamp-on gas flow measurement
- Power plants: Reliable measurement and monitoring of natural gas consumption
- Mechanical Engineering: Compressed air billing and consumption optimization
- Gas utilities: Replacement of mechanical meters on transmission pipelines or pressure reducing stations
- LNG terminals: gas acceptance, odor control
- Chemical and petrochemical industries: Safe flow measurement of hazardous and toxic gases
