OPTISWIRL 4200 has the capability to master fluctuating pressures and temperatures which turns it into an ideal all-rounder for the measurement of energy carriers in auxiliary and supply processes.Already the basic version of the OPTISWIRL 4200 is equipped with a temperature compensation for saturated steam applications. With the optional pressure sensor the flowmeter 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 this flowmeter to be a reliable partner for advanced energy management systems.
