Description:

The CM6G Gas Calorimeter is used to measure and control the calorific value or Wobbe Index (WI) of the sample gas. In this calorimeter, the sample gas is burnt at the burner with air and the temperature difference between the combustion exhaust gas and the feed air at the burner inlet is detected by using a thermocouple. This calorimeter detects the flow rate of both the sample gas and the air as the differential pressure by using the orifice and converts the differential pressure to the digital signal then compensates the flow rate variation by the digital calculation. This method gives an excellent high reliability, therefore it can be used for the control of thermal input for the various type furnaces in the steel mill and petrochemical industries, also for the calorie control of the town gas. * This product is not available in Europe.……

Description

CM6G

The CM6G Gas Calorimeter is used to measure and control the calorific value or Wobbe Index (WI) of the sample gas. In this calorimeter, the sample gas is burnt at the burner with air and the temperature difference between the combustion exhaust gas and the feed air at the burner inlet is detected by using a thermocouple.

This calorimeter detects the flow rate of both the sample gas and the air as the differential pressure by using the orifice and converts the differential pressure to the digital signal then compensates the flow rate variation by the digital calculation. This method gives an excellent high reliability, therefore it can be used for the control of thermal input for the various type furnaces in the steel mill and petrochemical industries, also for the calorie control of the town gas.

* This product is not available in Europe.

  • The construction of the detector is solid and durable, and easy for maintenance and operation.

  • Special patent construction is adopted at the mixing point of the heat exhaust gas and the heat absorbing air from the detector, and it improves the response time.

  • Excellent high reliability by using orifices to detect differential pressure both air and gas and to calculate after compensating the indication errors caused by the flow rate variations.
