Claim 0:
1. A system comprising:
a paint spray gun comprising, a spray tip having a tip orifice;
a pump comprising a reciprocating piston configured to pump paint along a flow path to the paint spray gun, wherein the spray tip atomizes the paint in an atomized spray pattern released from the tip orifice; and
a controller configured to:
detect a reciprocation speed of the reciprocating piston;
determine a pressure of the paint along the flow path;
determine a flow rate of the paint along the flow path based on the reciprocation speed;
determine a current tip orifice size of the spray tip based on:
the flow rate and the pressure of the paint; and

a mobile device configured to:
generate a comparison result based on comparing current tip orifice size to a first tip orifice size of the spray tip;
generate a wear value indicative of an amount of wear of the spray tip based on the comparison result; and
generate an output based on the wear value.
