NAF® Flow Calculation Software

NAF® Flow Calculation software is available for NAF® S 125 and NAF® S 227 Fire Extinguishing Systems. The agent calculation software represents a fundamental mean for the correct design of a fire protection system. It contains a sophisticated calculation routine for predicting the quantity of agent through a pipe network system. The calculation routine can be initiated when all the data necessary to describe the system has been input via the interface.

The Windows™ - based interface provides a convenient, fast and user-friendly method for entering the system. The software is also interfaced with (and dependent upon) the hardware-specific data that must be included in the design of a system. All the required information must be entered before a calculation can be run. The Isometric Entry Screen allows the user to "draw" a sketch of the system. Information from the drawing is automatically transferred to the Pipe Network Table.

Designing a system begins by entering information to calculate the quantity of agent required to be delivered into each hazard. An agent source (cylinders) and pipe network is then entered to deliver this agent. Nozzle codes may be either manually entered or estimated by the calculation routine to complete the layout of the system. The calculation routine is then run and a comparison of the system requirements to the predicted system performance is made. If the predictions meet the system requirements and no error messages are present, then the system is properly designed.
