7th Generation of Portalevel Mini by Coltraco Limited

The primary product launched by Coltraco was the Portalevel® in 1987, which now has diversified to extreme extent to cope the needs of people. The 7th Generation of Portalevel Range has been the most successful model in Coltraco Ultrasonic’s history with many thousands of units supplied across the world.

Through the constant evolution and refinement of our offering, the Portalevel Mini was created to offer customers an even more compact, versatile unit to further enhance the ease with which fire system can be tested. Offering totally hands free operation with the unit hanging around the operators’ neck, both hands are free to work with the trusted reliability offered by the 7th Generation. Here, a few features are enlisted which are provided with this portable ultrasonic level indicator.

Function of Portable Ultrasonic Liquid Level Indicator

The Portalevel MINI is the 7th generation unit of its kind. It is based on the Portamarine TM design with the key modification for hands-free use. Ideal for testing in difficult to access areas where hands free use is beneficial to enable the operator to move around the area more easily. The Portalevel® range is used for identifying the content of critical fire suppression cylinders. A wide variety of fire suppressant agents can be monitored including: CO2, Dupont, FM-200, NOVEC1230, old Halons such as 1301 and 1211, FE-13, FE-25, FE-36 and HFC-225 & 227. The 7th generation model is tailored to suit those operators who want a small, compact unit for easy testing. It is more accurate (to 1.5mm+/-), quicker and safer than weighing cylinders.

  • Portable: Lightweight small unit which comes with a durable, rugged case
  • Easy to Use: No formal training necessary, accessible to a wide range of audiences and is easy for existing Portalevel® operators to adapt to
  • Durable: The unit is housed in a solid plastic enclosure ideally suited to protecting the internal electronics, even if the unit is lightly dropped or slightly roughly handled.
  • SPA Feature: This liquid level indicator has this feature, which is used to increase the power output of the unit and increase the sensitivity of the unit when registering the return signal.

Integrity and Science Key to Our Culture of Performance

Dear Coltraco Customers, Strategic Partners and Distributors,

Integrity is our defining value. Performance is its consequence. We understand that our customers have choices, and how we perform determines whether customers choose us. Coltraco’s Code of Ethics does not merely require compliance with laws. It embodies a Commitment to positive behaviours that build trust, promote respect, operate with distinction, with courtesy and global levels of performance, demonstrating our integrity and delivering customer performance.

We honour our commitments, communicate transparently, and act with honour. Ethics are the foundation of our performance culture and our science-based approach. We lead in specific technologies delivering the watertight integrity monitoring of marine structures and the monitoring of fixed liquefied gaseous fire extinguishing systems and the room integrity of protected space to ensure agent hold-times post-installation. We show this by our understanding of the science in them and the mathematics that explain them.

I would like to thank you for your business and for the relationships with our Customers, Strategic Partners, Distributors and ODAs who we value so highly.
