I need some assistance....

What type of valve should i use for the tank infill? Should the tank infill line have a flow measuring device to monitor the rate of infill.

The above must be in accordance with NFPA std.

I?m not sure if the filling equipment should be listed for fire prot.?

In my case I?ve found lots of different filling sources that it is almost impossible to have full aproved components, so I have interpreted from NFPA that it must be endorsed by he AHJ or good criteria.

I suppose you are thinking of automatic valves with level control..., so think of float valves.

If you have mid or high pressure, or if you think of more control options, think of hydraulic control valves Bermad, OCV, Watts), for pressure reducing, float pilot operated level control.

I?ve never had a tank system that fils with pumps.

Think of strainers, emergency/manual bypass.

Sorry mates, but I have to admit that sometimes a fire protection engineer would not be the best choice to design a fire water tank filling system if it is not his field of expertise.
