The Steam Vortex Flowmeter is a specialized flow measurement device optimized for steam applications. Based on the vortex shedding principle, it accurately measures both saturated and superheated steam. By integrating temperature and pressure compensation, the meter directly outputs mass flow or standard volume flow, ensuring precise and reliable steam measurement under varying process conditions.
This type of vortex flowmeter is widely used in boilers, power plants, heating networks, and industries where steam is a critical energy source.
