Optiswirl 4200 vortex flowmeter can measure conducting and non-conducting liquids, gases and steam for monitoring energy flows of saturated and superheated steam or how water, and heat metering applications. IEC 61508 safety standard-compliant, it has one temperature sensor integrated as standard, and can be installed a a heat meter in the feed line, connected with an external temperature sensor in the return line. Gross and net heat calculations can be fed into a DCS to support advanced energy management.
