Daily Telegraph – ‘Letters to the Editor’

As one of the world’s first innovative portable ultrasonic liquid level indicator with a brand new dual certification, Coltraco Ultrasonic’s Portalevel® INTRINSICALLY SAFE (Portalevel® IS) meets stringent safety standards for explosive atmospheres, making it suitable for use globally in both Zone 1 and Zone 2 hazardous areas. The device measures liquid levels contained in fire suppression cylinders and other types of tanks stored in hazardous zone environments.

In the maritime industry, ensuring safety isn’t just a best practice—it’s a necessity. According to Lloyd’s List, almost 10% of all total losses at sea in the last decade were caused by fires onboard. As NTSB Chairman Robert Sumwalt rightly said, “Safety isn’t something you have, it’s something you do.” When lives are at stake, neglecting fire systems and their maintenance is simply unacceptable.

The Portascanner® WATERTIGHT PLUS generator fills the entire cargo hold with ultrasound. The receiver detects the smallest of ultrasonic signals so that leaks as tiny as 0.06mm can be located.
