A system includes a fluid spray gun comprising a spray tip having a tip orifice, a pump configured to pump fluid along a flow path to the fluid spray gun, and a monitoring system comprising one or more processors. The monitoring system is configured to obtain data indicative of a flow rate of the fluid along the flow path, obtain data indicative of a pressure of the fluid along the flow path, and determine a tip wear metric indicative of a wear of the spray tip based, at least, on the data indicative of the flow rate of the fluid along the flow path and the data indicative of the pressure of the fluid along the flow path. The monitoring system further controls a display screen to generate a display based on the tip wear metric.
