1. Core Principle (Kármán Vortex Street) When fluid flows past a non-streamlined vortex generator, alternating vortices are formed on either side, arranged in a regular pattern (Kármán Vortex Street). Vortex shedding frequency: f=St×vdf = St times frac{v}{d} StSt : Strouhal number (approximately 0.16–0.22, stable within Reynolds number 2×1032 times 10^3 to 7×1067 times 10^6 ) […]

Process engineers often compare the inlet and outlet flow rates of equipment, devices, or pipelines to ensure the stability, safety, and efficiency of production. The key reasons for this practice can be explained from the following perspectives: 1. Verifying Material Balance to Ensure Process Stability In industrial production, the input-output-accumulation of materials in equipment or

1. Proximity Sensing Proximity sensing involves detecting the presence or absence of an object, as well as its size or simple shape. Proximity sensors can be classified into contact and non-contact types and operate in either analog or digital modes. The choice of sensor depends on physical conditions, environmental factors, and control requirements. Common types
