I supervise a shop where we have a piece of equipment that uses water to test aircraft parts to ensure structural integrity. However, I cannot find a way to keep the water pressure the same at each nozzle (there are 4 nozzles) Is there a gauge or tool that will measure the "exit" water pressure out of a nozzle? It would be like measuring the "exit" water pressure out of your garden hose.
