The Portasteele® CALCULATOR provides the perfect companion to the Portalevel® Technology for those looking to convert liquid height to agent mass and export reports to customers.

The Portasteele® CALCULATOR provides a quick and easy method for calculating the agent mass from the liquid level of any agent. By simply inputting the cylinder dimensions, agent type, temperature and liquid level, the unit will instantly calculate the exact agent mass within the cylinder, accurate to less than 1%. All the data is pre-loaded onto the device so no manual calculation is required by the operator. This can be especially useful for companies inspecting a wide variety of different cylinders or when winning new servicing contracts.

When used in partnership with the Portalevel® technology, the Portasteele® CALCULATOR can log and record the results from each cylinder being inspected. The device then produces a comprehensive report, with all results time stamped, showing the exact agent quantity within each cylinder, the deviation of agent weight from the supposed fill weight and highlighting those cylinders which are underfilled and require attention. This record can then also be provided to the customer, providing a key servicing advantage or provide an easy internal record of testing.

All cylinders with different agents, manufacturers or dimensions can be loaded onto the device and data for all common fire suppressant agents is preloaded.

Three Core Benefits:


1. FIRST IN THE WORLD - The Portasteele® CALCULATOR is the first in the world to provide agent weight readings without physically weighing the fire suppression cylinders to comply with fire safety regulations.

2. HIGHLY ACCURATE - It takes into account the dimensions of practically any cylinder, the type of agent being measured and the ambient temperature therefore providing accurate results in a variety of conditions.

3. SAVE COST OF MAN HOURS - Decreasing the time to regularly and effectively test cylinder agent weights, when paired with a liquid level indicator, Portasteele® CALCULATOR will reduce the inconvenience and costly man hours required for testing.
