Abstract
A system for managing liquid supply suitable for a process equipment with a liquid tank is disclosed. The system includes a host, a data-reading tool, a system controller and a tank-locking device. The host stores a built-in liquid database. The data-reading tool used for reading data related to the liquid tank is electrically connected to the host. The host receives the data related to the liquid tank from the data-reading tool, and the received data mapped with the liquid database. The system controller drives the tank-locking device according to the signal from the host to whether or not allow replacement of the liquid tank.
