Abstract
A method and system are provided for detecting blockage in a spray gun of a liquid spray system wherein a first transducer is positioned to detect the pressure of paint or sealer in a supply line at an upstream position and a second transducer is positioned immediately adjacent and upstream a spray orifice of a spray gun to detect a second pressure of the liquid wherein a pressure drop of the liquid is calculated and a blockage signal is generated when the pressure drop is less than a predetermined amount. Preferably, the line and the spray gun are sized so that pressure drop is at least 10 psi and preferably approximately 350 psi in the absence of any blockage.
