  • Publication number: 20240019410
    Abstract: First sensor data indicative of a first mass flow rate of a first gas flowing to a vaporization chamber is received. The vaporization chamber includes a compound and is to transition the compound into a gaseous state. Second sensor data indicative of a second mass flow rate of a second gas including the compound and the first gas flowing out of the vaporization chamber is received. Third sensor data indicative of a third mass flow rate of the compound into the vaporization chamber is received. The first sensor data, the second sensor data, and the third sensor data is processed using a trained machine learning model to determine an estimated concentration of the compound within the second gas. At least one of a) modifying a flow rate of the first gas or b) providing the predicted concentration for display by a graphical user interface (GUI) is performed.
