Coltraco Ultrasonics, a global leader in precision ultrasonic technology, is proud to launch two revolutionary products: the Portalevel® LITE and Portalevel® ADVANCED. These two new offerings mark the 12th generation of Coltraco’s pioneering ultrasonic liquid level indication technology, further cementing its position as an unmatched leader in the field.
Building on over 30 years of expertise, Coltraco Ultrasonics again showcases its commitment to innovation, reliability, and precision.
Designed for the modern demands of fire suppression system maintenance, the Portalevel® LITE and Portalevel® ADVANCED join the company’s award-winning range, which includes the highly respected Portalevel® MAX PLUS and Portalevel® IS.
Setting the Standard: Why Monitor Fire Suppression Systems?
Gaseous fire suppression systems protect critical assets across marine, defence, power generation, and high-value infrastructure sectors. They are under constant dynamic pressure. Over time, these systems are susceptible to leaks, reducing their ability to achieve design concentration during a fire emergency.
Given the narrow safety margin within which they operate, even a minor fault can have serious consequences for safety, property, and life.
As the value of protected assets continues to soar, the need for practical, reliable, and regular maintenance of fire suppression systems has never been more critical. Unfortunately, in many industries, fire safety is viewed as a cost, rather than the investment it truly is.
Coltraco Ultrasonics addresses this vital need with their advanced ultrasonic technology, designed to “see the sounds that others cannot hear” and “measure the hitherto unmeasurable.”
