Portatank® is a handheld, portable, and battery powered liquid level indicator designed to non-invasively, accurately, and reliably measure the level of liquid within a tank. Portatank® is suitable for application on vessels from 0.5m to 15m in diameter and can reliably detect the level of most clean liquids in metal, plastic, or glass vessels. It is also commonly used to detect oil levels in transformers in both pole mounted or pad mounted transformers.

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.
