Portable Clamp-on Ultrasonic Gas Flow Measurement

Dive into the field of high-precision, non-contact ultrasonic gas flow measurement with the deltawaveCoG from Systec, Germany:

• accurate clamp-on gas (CoG) flow measurement that seamlessly combines ease of use and careful attention to airflow and gases in pipeline
• the latest technologies in compressed air monitoring and natural gas flow measurement
• using a non-intrusive, clamp-on method that ensures the operational integrity of the pipeline

The ultrasound gas flow meter transducers are mounted on the outside of the pipe, allowing processes to continue undisturbed and maintaining the integrity of the pipe. This technology provides 100% leak- and wear-free gas flow measurement and constant compressed air monitoring.

To ensure accurate and comprehensive data acquisition, ultrasound gas flow meter deltawaveCoG is also an integrative volumecorrector, 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.

• 100% contact-free with the medium
• 100% wear-free
• 100% leak-proof
• 100% hygienic
• 100% pressure loss-free
• high minimum pressure for steel pipes (min 6-15 bar) and plastic pipes (min. 1 bar)
• Suitable for DN25….DN700

Navigating in hazardous areas, our ultrasonic flow meter for gas 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.

Measuring principle: Working principle clamp on ultrasonic gas flow meter Systec

Ultrasonic transit time difference method (Clamp-On) – For this purpose, two ultrasonic transducers are mounted on the pipeline from outside and connected to the evaluation electronics.
The ultrasonic transducers work alternately as transmitters and receivers and send ultrasonic signals at each other. These signals are accelerated or decelerated by the medium flow. The resulting difference in the two signal propagation times is proportional to the flow rate and is used together with the pipeline geometry for the precise calculation of the flow rate.

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
