An improved particle blasting apparatus for continuously monitoring media flow, nozzle wear, and nozzle blockage. The apparatus includes a source of compressed air, a nozzle, structure for conveying the compressed air from the source to the nozzle in an airstream, structure for introducing the media into the airstream to be carried by the airstream, and an air flow rate meter in the air conveying structure to indicate the air flow rate therein. In a preferred embodiment, indicator lights are included which are illuminated if the air flow rate falls outside of an acceptable range. A method of using the particle blasting apparatus is also disclosed.

An improved particle blasting apparatus for monitoring media flow, nozzle wear, and nozzle blockage, said equipment having a source of compressed air, a nozzle defining a restricted opening, means conveying said compressed air from said source to said nozzle in an airstream, and means operatively connected to said air conveying means introducing particle blasting media into said airstream, whereby said media is carried through said nozzle by said airstream, wherein the flow rate of said airstream through said air conveying means is affected both by the amount of said media introduced into said airstream and by the effective size of said restricted opening in said nozzle, wherein the improvement comprises air flow metering means operatively connected to said air conveying means indicating said flow rate through said air conveying means, whereby insufficient media introduction and an excessive size of said restricted opening increases said flow rate causing said metering means to indicate an excessive flow rate greater than a predetermined maximum parameter, and whereby excessive media introduction and blockage of said nozzle reduces said flow rate causing said metering means to indicate an insufficient flow rate less than a predetermined minimum parameter.
