Overview

Delivering Safesite® For All Budgets

Portalevel® LITE quickly and accurately determines the liquid level in a wide range of liquefied fire suppression agents, including CO2, FM200™, and NOVEC™1230. The device features a high-contrast OLED display that clearly indicates the cylinder contents phase, showing either “GAS” or “LIQUID.”

With over 30 years of experience in developing ultrasonic liquid level indicators, Coltraco Ultrasonics is a leader in this field. Portalevel® LITE uses advanced signal processing techniques to deliver liquid level accuracy to within ±1mm of the true level. Our instruments are crafted to the highest standards in the UK using premium materials, offering superior value and reliability, backed by our unique position in research and development.

Key Features

Optimised Rectangular Sensor: Enhanced design directs ultrasound more effectively, improving accuracy and measurement efficiency.
Advanced Signal Processing: New algorithms provide clearer differentiation between gas and liquid phases, ensuring precise results.
Faster Testing: Simplified procedure with clear GAS/LIQUID indication for quicker operation, reducing testing time.
Extended Battery Life: 24 hours (est.) of continuous use on standard AAA batteries, with an automatic power-saving mode after 10 minutes of inactivity

Advantages:

Portable & Versatile: Quickly measures cylinders of various sizes and types.
Non-invasive: No system downtime, ensuring safe and continuous operation.
Rapid Measurement: Provides results in under 30 seconds—significantly faster than traditional methods like weighing.
Long Battery Life: 24 hours of use on AAA batteries with easy replacement.
Clear Display: The intuitive OLED screen clearly shows the cylinder contents, whether “GAS” or “LIQUID.”
Lifetime Support: Coltraco Ultrasonics provides continuous technical support throughout the product’s lifecycle.

Agent Weight Calculation with Portasteele®

The combination of the Portalevel® ADVANCED and Portasteele® CALCULATOR uses our decades of experience in ultrasonic engineering and collaboration with fire suppression system manufacturers to allow a user to clearly determine the agent weight from the liquid level without having to physically weigh the cylinder. The benefits of this are:

Tracebility: The liquid level found is traceable to the agent weight which is the only documented evidence of fire suppression cylinder contents from the manufacturer

Temperature Correction: Any fluctuations in liquid level as a result of temperature changes is automatically accounted for in the calculations, giving you the true agent contents at all times regardless of temperature

All measurements are saved and recorded with time & date stamp, for effectively audit trail and to comply with relevant ISO and NFPA regulations where agent weight is required to be reported

Frequently Asked Questions

The Portalevel® LITE is a handheld ultrasonic device used to quickly and easily measure the liquid levels inside fire suppression system cylinders. It provides a cost-effective solution for maintaining fire safety compliance without the need to dismantle or weigh cylinders.

The Portalevel® LITE is designed for basic, routine servicing where a simple, reliable, and affordable solution is required. While it shares the same core ultrasonic technology as more advanced models, it offers essential functionality at a lower price point, making it ideal for less frequent inspections or smaller operations.

The Portalevel® LITE can detect liquid levels in cylinders containing agents like CO₂, FM-200®, NOVEC™ 1230, FE-13™, and similar suppression systems. It is compatible with a wide range of pressurized gas cylinders commonly used in commercial, marine, and industrial fire protection.

The Portalevel® LITE offers an accuracy of ±1.5 mm, allowing reliable identification of the liquid level inside cylinders. This helps ensure fire suppression systems are maintained properly, supporting regulatory compliance and operational safety.
