The Krohne OPTISWIRL 4070 Vortex Flowmeter is a durable, 2-wire multivariable device built for reliable measurement of steam, gases, and liquids in tough industrial settings. Its fully welded stainless steel construction resists corrosion and withstands high pressures up to 100 bar and temperatures to 240°C, making it perfect for steam applications in power plants and refineries. With integrated pressure and temperature sensors, it calculates mass flow directly, reducing the need for multiple devices. Supporting HART and FOUNDATION Fieldbus, the OPTISWIRL 4070 ensures seamless integration and low maintenance for enhanced process efficiency.
