At Coltraco Ultrasonics, we understand how critical it is for your industry to maintain accurate, reliable, and compliant liquid level monitoring. The systems you protect – from fire suppression units to industrial tanks – must perform without fail.
That’s why selecting the right ultrasonic level device is not just a technical decision, but an operational priority.
Our Portalevel® Range has been engineered to address specific industry challenges. Whether you’re managing safety at sea, protecting data centres, securing defence assets, or operating in hazardous energy environments, we have a solution designed to support you.
Why Liquid Level Accuracy Matters
Across every sector we serve, maintaining liquid level accuracy is essential to safe operations and regulatory compliance. An underfilled or leaking cylinder can lead to catastrophic failure, environmental exposure, or audit non-conformance.
Traditional measurement techniques, such as weighing cylinders or dismantling units, are time-consuming and often disruptive.
By applying ultrasonic technology, our Portalevel® Range allows you to verify the contents of pressurised vessels in a non-invasive, accurate, and efficient way.
This supports fast, repeatable spot checks that reduce downtime, improve safety, and meet the requirements of international standards such as ISO 14520, NFPA 2001, and IMO SOLAS.
Understanding the Differences Between Our Technologies
- The Portalevel® Range includes several instruments tailored to different applications:
- Portalevel® MAX PLUS – our most widely used device for everyday inspection of gaseous fire suppression cylinders.
- Portalevel® MAX MARINE PLUS – engineered for marine vessels, with a slimline extension rod for accessing tightly banked rows of cylinders.
- Portalevel® ADVANCED – designed for more complex systems, including larger-diameter cylinders and applications requiring higher precision.
- Portalevel® Intrinsically Safe – ATEX-certified for hazardous and explosive environments.
All are built for ease of use, durability, and compliance, allowing technicians to conduct inspections quickly, safely, and without shutting down systems.
Supporting Safety at Sea
The shipping industry faces unique fire safety challenges. Effective suppression systems must safeguard engine rooms, pump stations, cargo spaces, and accommodation areas.
SOLAS regulations require that these systems be routinely inspected to confirm agent presence and correct pressure.
With ultrasonic technology, operators can verify the contents of CO₂ cylinders and clean agent systems such as NOVEC™ 1230 and FM-200®, which have a measurable liquid phase. (Inert gas systems, such as Inergen®, do not have a liquid phase and therefore require alternative testing methods, such as our Portagas® device.)
The Portalevel® MAX MARINE PLUS is designed to simplify inspections for marine operators. Its slimline extension rod makes it easy to test cylinders arranged in tight banks without dismounting or weighing them.
Recommendation: For marine compliance, choose the Portalevel® MAX MARINE PLUS.
Monitoring Mission-Critical Systems in Defence
Defence operations demand resilience. Suppression systems in land vehicles, naval assets, and secure facilities must always be at full capacity, with no room for uncertainty.
The Portalevel® Range enables one-person, non-invasive inspections of FM-200® and NOVEC™ 1230 systems in minutes, without depressurisation or downtime.
For hazardous zones and explosive environments often encountered in defence contexts, the Portalevel® Intrinsically Safe is the instrument of choice. Its ATEX certification ensures safety in environments where standard equipment is not permitted.
Recommendation: For defence and hazardous operations, choose the Portalevel® Intrinsically Safe.
Protecting Data and Infrastructure
Data centres, telecoms hubs, and secure buildings must be protected against even minor fire events. Suppression systems are only effective if cylinders are correctly filled and ready.
Facility managers rely on the Portalevel® Range for non-invasive inspections that comply with ISO 14520 and NFPA 2001, without interrupting services or removing cylinders from operation.
The Portalevel® ADVANCED provides higher accuracy and a wider operating range for larger cylinders often found in critical infrastructure settings.
Recommendation: For critical infrastructure and data centres, choose the Portalevel® ADVANCED.
Optimising Monitoring in Oil and Gas
Oil, gas, and petrochemical facilities present some of the harshest operating environments, where safety and compliance are paramount.
Platforms, refineries, and storage terminals depend on fire suppression systems to protect personnel and assets from catastrophic risks.
Here, portability, durability, and certification are essential. The Portalevel® Intrinsically Safe suits hazardous energy environments where ATEX-rated equipment is mandatory.
Recommendation: For oil and gas facilities, choose the Portalevel® Intrinsically Safe.
Matching Technology to Industry Needs
Selecting the right liquid level indicator depends on your operational environment:
- Marine → Portalevel® MAX MARINE PLUS for inspections in confined cylinder banks.
- Defence → Portalevel® is intrinsically safe for hazardous and explosive zones.
- Critical Infrastructure → Portalevel® ADVANCED for large-diameter and complex suppression systems.
- General Fire Safety → Portalevel® MAX PLUS for day-to-day inspection across multiple sectors.
You gain faster inspections, safer processes, and full compliance assurance by tailoring the instrument to the application.
