It adds power points to your warframe, so you can use skills more often without having to find blue orbs on regenarate it with energy siphon. But the percentage it adds is based on your base power, so a warframe that has 100 power at level 0 will get only 25 extra power points from the Flow Mod that hasn't been upgraded, even if the warframe is already level 30.
