Sprays and nozzles are used in a wide range of industries with a variety of applications. In all these applications the spray droplet size is the most important characteristics. The droplet size determines the amount of liquid sprayed as a result improper spray can cause significant damage to the process. Currently there are different methods for spray size measurement with Laser or Phase Doppler Velocimetry methods as the most common. However, these are complex and expensive. In particular, it is impossible to use these facilities without highly trained personnel and it is impossible to do field tests.

喷雾器和喷嘴用于具有各种应用的广泛行业中。在所有这些应用中，喷雾液滴尺寸是最重要的特性。液滴尺寸决定了喷射的液体量，因此不适当的喷射可能会对工艺造成重大损害。目前有不同的方法用于喷雾尺寸测量，激光或相位多普勒测速法是最常见的方法。然而，这些是复杂和昂贵的。特别是，如果没有训练有素的人员，就不可能使用这些设施，也不可能进行实地测试。
