  • Patent number: 11353894
    Abstract: A liquid processing apparatus includes: a substrate processing unit; a supply line that supplies the fluid to the substrate processing unit; a flow meter that measures a flow rate of the fluid flowing through the supply line; a flow rate adjustment mechanism that adjusts the flow rate of the fluid flowing through the supply line; and a controller that control the flow rate adjustment mechanism based on a measurement result of the flow meter. The controller receives the measurement result at a first cycle. When the measurement result of the flow meter indicates that the flow rate of the fluid flowing through the supply line is included in a preset range, the controller causes the flow rate adjustment mechanism to adjust the flow rate of the fluid flowing through the supply line at a cycle having a time interval longer than a time interval of the first cycle.
