A Vortex Flowmeter is designed to measure the volumetric flow of liquids. It operates based on the vortex shedding principle, where fluid passing over a bluff body generates alternating vortices. The frequency of these vortices is directly proportional to the flow velocity. With no moving parts, vortex flowmeters are ideal for high-temperature and high-pressure applications.
Commonly used in chemical, power, HVAC, and oil & gas industries, they offer accurate flow measurement with minimal pressure drop and are available with analog or digital outputs.
