Exhaust Gas Calorimeter ThermoFlux – 7105
Product Overview
Exhaust Gas Calorimeter ThermoFlux – 7105 is a laboratory apparatus for determining thermal exhaust gas losses of internal combustion engines using the exhaust gas calorimeter method of calorimetric measurement. The unit consists of an insulated stainless steel tank with an internal looped finned pipe heat exchanger. Exhaust gas flows from bottom to top through the tank, transferring heat to cooling water circulating through the finned pipe. Heat exchange area on the exhaust gas side is 1.169 m²; on the water side, 0.164 m². Four temperature sensors record exhaust gas and water inlet and outlet temperatures (-100 to 400°C each pair). A flow meter records water flow rate (4 to 36 LPM). All values are recorded electronically and displayed digitally via a measuring amplifier. The engine connects to the unit via an exhaust gas hose. Specific heat capacity of the exhaust gas can also be …

Construction and Design
The Exhaust Gas Calorimeter ThermoFlux – 7105 is built around an insulated stainless steel tank that forms the primary heat exchange enclosure. Exhaust gas from a test engine enters at the base of the tank and flows upward through the interior.
Inside the tank, a finned pipe heat exchanger carries cooling water. The pipe is arranged in loops to achieve the maximum possible heat exchange area. The heat exchange area on the exhaust gas side is 1.169 m² and on the water side is 0.164 m². As the exhaust gas flows upward past the finned pipe, it gives up its heat almost completely to the cooling water. The insulated tank construction minimises external heat losses, ensuring the exhaust gas calorimeter delivers a largely complete and loss-free measurement of the exhaust gas thermal output.
Four temperature sensors measure exhaust gas temperature at the inlet and outlet and water temperature at the inlet and outlet. A flow meter records the cooling water flow rate over the range 4 to 36 LPM. All sensor signals are recorded electronically. A measuring amplifier with digital displays presents all values for direct reading and calculation. The engine connects to the calorimeter via an exhaust gas hose.

Frequently Asked Questions
Q: What does the Exhaust Gas Calorimeter ThermoFlux – 7105 measure?
A: The unit determines the thermal output power of exhaust gases from internal combustion engines using calorimetric measurement. It records exhaust gas inlet and outlet temperatures, cooling water inlet and outlet temperatures, and water flow rate. These values enable calculation of the heat given up by the exhaust gas, the engine energy balance, and the specific heat capacity of the exhaust gas.
Q: What are the heat exchange areas in this exhaust gas calorimeter?
A: The heat exchange area on the exhaust gas side is 1.169 m². The heat exchange area on the water side is 0.164 m². The finned pipe is arranged in loops inside the insulated stainless steel tank to maximise the available heat transfer area.
Q: What temperature and flow measurement ranges does the unit cover?
A: Exhaust gas temperature is measured over 2 x -100 to 400°C. Water temperature is measured over 2 x -100 to 400°C. Cooling water flow rate is measured over the range 4 to 36 LPM.
Q: How is the engine connected to the calorimeter?
A: The test engine is connected to the calorimeter unit via an exhaust gas hose. Exhaust gas enters at the bottom of the insulated stainless steel tank and flows upward through the heat exchanger.
Q: How are measured values displayed on the ThermoFlux – 7105?
A: All measured values are recorded electronically and displayed digitally using a measuring amplifier with digital displays. The amplifier processes signals from all four temperature sensors and the flow meter simultaneously.
