For atmospheric pressure storage tanks pumped using pumps, how can automatic control settings be used to ensure that the tank is emptied completely each time? In addition to the liquid level, there is also a flow meter at the pump outlet; can it be determined at what point the flow rate at the pump outlet falls below the set value, indicating that the storage tank has been emptied?
No, when it’s about to run out of fluid, the pump’s flow rate becomes unstable. If the tank has a large diameter, there will be a lot of residue left; in such cases, a test gauge can be installed
