The Portalevel® is the ultrasonic liquid level indicator, designed and manufactured by Coltraco Limited for checking the content of fire suppression cylinders of CO2, FM200, NOVEC and all other Clean Agent or Inert Gas extinguishing liquids.
Coltraco Limited has been designing such equipment since 1989 and was the first company to use the concept of using ultrasonic technology, as an alternative method to weighing or using radioactive devices to check cylinder content. Since our original design, we have created seven generations of Portalevel units and drawing on this experience has allowed us to create the world leading product of its type worldwide with over 15,000 units in operation in 104 countries.
The Portalevel is the only ultrasonic liquid level indicator to have been awarded full Classification Society approval and has been proven to locate a liquid level with an accuracy of +/- 1.5mm.
