VIKING EMEA and Coltraco Ultrasonics partner on a custom ultrasonic liquid level indicator
Coltraco and Viking EMEA are delighted to provide the firefighting market with the first FM approved Non invasive Ultrasonic Liquid Level Indicator
Portamarine® is a low-cost, portable, and battery powered liquid level indicator designed to non-invasively, accurately, and reliably measure the level of fire suppression agent contained within a cylinder. Portamarine® is suitable for most standard size cylinders containing CO2, Liquified Clean Agents and Halons and is specifically equipped for use onboard marine vessels and environments in the marine sector.

Portamarine® is the ideal low-cost solution for testing marine fire suppression systems. Its tried-and-tested ultrasonic technology allows it to provide reliable test results to ±1.5mm for most CO2, Halon, and Clean Agent fire suppression systems. It is non-invasive and portable, meaning that a single operator with one Portamarine® unit can test an entire bank of cylinders of varying sizes and agents. The quick, easy, and accurate measurement process using Portamarine® allows for greater operational efficiency and a streamlined testing process with no downtime for the fire suppression system. Without the need to weigh and dismantle cylinders, contents can be checked safely and reliably by the crew themselves.
Portamarine®’s non-invasive nature also removes any risk of accidental discharge, since it does not need cylinders to be disconnected and dismantled. When used alongside the Portasteele® CALCULATOR, the agent weight can be determined from the liquid level, meaning that an operator can calculate the amount of agent within a system without having to physically weigh cylinders. This allows for a faster, safer, and more efficient way to comply with marine safety standards like IMO SOLAS FSS Code and MSC.1/1318.
The Portamarine® is designed specifically for the marine industry:
