Does anyone have a good procedure for flow testing (both air and water) industrial gas turbine fuel nozzles?

RE: Industrial gas turbine fuel nozzles
Type of fluid is specified (usually a calibrating fluid, per some MIL or ASTM or equivalent spec.), temperature range and supply pressure. Lower and upper flow limits (usually in mass flow units) are set for these conditions and the actual testing is rather simple.
A pump capable of supplying let say 50% larger flow at that pressure or the original pump is required, an adequate flow-meter would be nice, a thermometer and that is it. If there is no flow-meter than a calibrated vessel with a volume scale and a chronometer are required to measure (calculate) the volume flow rate. Sometimes it may be necessary to preheat the fluid or to cool the flow. But I have never heard that air or water is utilized for the testing, not for flying gas turbines.
For some nozzles even desirable spraying pattern is defined. Therefore it is not sufficient to meet quantitative limits only but qualitative also. I doubt that something like it is necessary for large gas turbines’ (not aero-engine derivatives). I believe that their nozzles are more like burners, well I might be wrong about that.
