Online Calorimeters for Highly Accurate Heating Value Measurement

Thermo Fisher Scientific (USA) announce the new Thermo Scientific Flo-Cal 6000 and 8000 online, high-speed calorimeters designed to accurately measure the heating value of combustible gases for refineries and related facilities, landfill operations and steel plants. Both models build on the fieldproven reputation of the Flo-Cal line and Thermo Fisher Scientific’s process instruments portfolio, offering key features to improve efficiency, plant safety and cost control.

Designed to rapidly measure the heating content of gas streams in Wobbe Index, Calorific Value and/or Specific Gravity, the Flo-Cal 6000 and 8000 are ideal for monitoring the heating value of combustible gases, blended gas streams and gas heating value quality. The new calorimeters are easy to use and calibrate, feature upgraded electronics to allow for unattended operation and have no moving parts to minimize maintenance.

Both models are also now uniquely designed to integrate with the Thermo Scientific Sarasota FD900 gas density meter, creating one highly accurate system for Calorific Value and Specific Gravity measurement to further
minimize maintenance and operational costs. The combined systems guarantee accuracy of .1kg/m3 for density and are capable of achieving specific gravity measurement of 0.1% of full scale.

“Our customers need instruments that help maximize productivity and reduce costs across the board. Both Flo-Cal models directly measure heating value by complete combustion of the sample gas, making the instruments less susceptible to gas compositional changes than other measurement techniques,” said Doug Frye, product manager for Thermo Fisher Scientific. “The instruments also enable more efficient furnace control, an industry trend that leads to operational cost reductions, and help control un-combusted hydrocarbons to minimize environmental emissions.”

The Flo-Cal 6000 and 8000 fully integrate with the Modbus communications protocol to ensure seamless integration with plant control systems, offer 4-20mA outputs to ensure plant safety and are available in hazardous-area designs or climate-controlled packaging. They are also backed by the extensive worldwide Thermo Fisher Scientific service and support network.
