The Portasteele® CALCULATOR is the perfect partner to any of Coltraco Ultrasonics’ liquid level detectors. It allows you to convert your measured liquid level to an agent weight, precisely and accurately. These readings can then be saved and exported for future reference and traceability.

Ultrasonic liquid level detection is a considerably more practical means of monitoring the contents of your fire suppression cylinders than removing and individually weighing each cylinder. It is quicker, easier and, as it avoids any down time of your fire suppression systems, safer than the alternatives. However, cylinder manufacturers do not provide the liquid level of a filled cylinder; the only documented evidence of a cylinder’s contents is its fill weight. Furthermore, the liquid level will fluctuate with temperature, as the density of the liquid changes. This will happen by different amounts for different agents and cylinder sizes and, therefore, is not trivial to predict.
The Portasteele® CALCULATOR solves both of these issues. Using dimensional data about the cylinder provided by the user and the liquid level found with one of our Portalevel® units to precisely calculate the agent weight. This Portasteele® CALCULATOR automatically handles the effect of temperature in its calculations and allows you to reliably calculate the mass of agent in your cylinder to within 1% of the true value. This allows your liquid level measurements to be compared directly to the fill weight printed on the cylinder providing you with unparalleled traceability to your liquid level measurements.
Smart data recording
The Portasteele® CALCULATOR is designed for use with cylinders containing liquified agents, where there are distinct liquid and gas regions in the cylinder. However, there are a number of agents, such as CO2 and FE-13, which have what is known as their “critical point” within standard atmospheric temperatures, when stored at pressure. When a substance reaches its critical point, it ceases to exist as distinct layers of liquid and gas and becomes something known instead as a “supercritical fluid”. When this occurs, it is no longer possible to use the liquid level to monitor contents, as there will be no liquid level.
The Portasteele® CALCULATOR takes away the option to record data for substances that will likely be in this state. For CO2, for instance, this critical point occurs at 31°C, so if a user inputs a temperature in excess of this, the Portasteele® CALCULATOR will present an error and they will not be able to proceed and save this measurement.

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.
