The OPTISWIRL 4200 is the first vortex flowmeter to feature integrated pressure and temperature compensation in 2-wire technology.
The OPTISWIRL 4200 provides reliable measurement of operating, standard volumetric and mass flow of conductive and nonconductive liquids, gases and vapours, even with fluctuating pressures and temperatures.
The OPTISWIRL 4200 was designed for the safety-related applications from the very beginning. It was developed according to the standard IEC 61508 edition 2. The certification is effected within the scope of a Full Assessment by TÜV Süd. Thereby the OPTISWIRL 4200 can be used for continuous volume flow measurement in safety-related applications with classification SIL2.
