Fenceline Monitoring

Open Path and Fenceline Gas Sensing

TAS was formed specifically to promote open path and fenceline monitoring using remote sensor technologies by developing methods and applications. TAS has developed methods and practices and set the bar for efficient and effective open path sensor systems.

TAS Remote Sensing Legacy

TAS began in 1992 to develop adoption of open path remote sensing instruments for industrial monitoring systems. Before anyone else, TAS began developing techniques and integrated systems to make these research tools part of industry hardened applications. These systems use spectrophotometry to detect hazardous gases in real-time. Light beams projected over a line of sight path, can detect these gases and measure the path concentration. Coupled with data management and applications techniques, open path sensing technology offers real-time detection and continuous monitoring of many hazardous gases.

TAS systems and methods have spread around the globe to a growing market. Manufacturers and integrators follow TAS methods, or often they are forced to rework troubled projects; unfortunately, TAS has supported many of these reworks. Decades of experience fielding emerging technologies such as open path gas sensing sets TAS above all the rest.

TAS Unique Qualifications in Fenceline Monitoring

Decades of experience makes TAS is uniquely qualified to design, field, and manage optical remote sensing systems for industrial applications. Open path sensors are highly versatile and can cover anything from small targeted spaces to very long paths monitoring large areas.

Light projected through the sample path measures industrial gases as they move through. This kind of measurement could present a number of challenges and perspectives to standard engineering practices. However, TAS understands this and is accustomed to building reliable systems and applying them to useful applications.

TAS fielded the first permanent fenceline monitoring system using multiple open path technologies. TAS has since fielded dozens of open path, fenceline, and other optical sensing systems in many industries and environments. A recent California initiative required petroleum refiners to install perimeter monitoring, also known as fenceline monitoring, and most of them were directly or indirectly designed around TAS standard practices. Optical remote sensors have come of age, and this remains the core of TAS business.

TAS is uniquely qualified to design, field, and manage optical remote sensing open path and fenceline systems for industrial applications. None come close to the TAS experience and application innovations.

TAS has a creative group of engineers, scientists, designers and technicians that understand the technology adoption challenges. Designing and fielding fenceline monitoring for reliable operation of these systems is a TAS legacy. None come close to the TAS experience and application innovations.

TAS Fenceline Monitoring Applications and Systems

Adoption of open path and fenceline sensing technologies has required development of relevant and effective applications and continuing support of integrated systems. TAS identified system design and support as a problem for technology adoption and determined to be the solution. TAS understands each project peculiar application needs, supports design and engineering to address them, and continues to support the entire system. Addressing these unique applications are normal for TAS. The list of accomplishments is long.
