The KROHNE OPTISWIRL 4200 Vortex Flow Meter is equipped with a temperature compensation for saturated steam applications. With the optional pressure sensor the OPTISWIRL 4200 has an integrated density compensation available, which even allows an exact measurement of gases and superheated steam with varying process conditions. The additional integrated gross and net heat measurement makes the OPTISWIRL 4200 to be a reliable partner for advanced energy management systems.

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.

Applications include measurement of saturated steam and superheated steam, steam boiler monitoring, heat metering of steam and hot water, measurement of consumption of industrial gases, measurement of consumption in compressed air systems, monitoring of compressor output, evaluation of Free Air Delivery (FAD), SIP and CIP processes in the food, beverage and pharmaceutical industries, and safety-related measurement in SIL applications. Available in connection sizes from 1/2" to 12" with ASME pressure classes 150, 300, and 600lb. Advanced technology for signal filtering ensures reliable measurement, and the integrated reduction of nominal size simplifies installation. Comprehensive communication options are available with field mount capability and cable length up to 164ft (50m). The meter measures both conductive and non-conductive liquids, gases and steam.
