The function of priming devices is to:

Explanation:
Priming devices establish the pump’s prime by removing air from the pump and suction line and filling the system with water. This allows a centrifugal pump to develop suction and start pumping, because without a prime air pockets would keep water from being drawn into the impeller. Once the pump is primed, it can draw water from the source and deliver it through the discharge. The other listed ideas aren’t the function of a priming device: it isn’t primarily a visual indicator, a device to limit discharge pressure, or a tool for calculating friction loss.
