Process Gas Calorimeter Meter and Controller

Arelco ARC (France) has the pleasure to announce the release of the new Combustible Gas Analyser CGA100, designed to monitor the quality of all combustible gases (Fuel gas of refinery, Coke oven gas, Blast Furnace Gas, Biogas, Natural gas, LPG, Blending of gases) by determination of Combustion Air Requirement Index (CARI), the Wobbe index, the Heating Value and the Specific gravity.

The CGA100 is the latest version of the Combumatic process calorimeter, a concept developed by Gaz De France and Arelco ARC and a proven solution over 30 years of use to contribute to the energy saving.

The new CGA100 is easy to use, the touch sensitive display allows the user to see very quickly all parameters and the instrument integrates some data logging facilities (Alarms, calibration results, configuration…). It
gives a complete traceability on the events that occurs on the analyser. The automatic calibration function gives the following possibilities: calibration on 2 up to 4 points, calibration cycles with malfunction detection
related to the calibration. The CGA100 integrates an accurate density meter based on measurement of frequency of vibrating element to improve overall accuracy by density corrections. The density is also available on a 4-20mA for customer use. The analyser gives a large effective measuring range with span extension and 2 analogue outputs up to 4 corresponding to user selectable parameter. All these data are available directly on the display or with the Modbus RS485.

The CGA100 is suitable for installation in safe or hazardous area zone 1 & 2 and ARELCO ARC can provide the sampling system and in option the ‘’CARI control system ‘’ with modulated injection of air in the gas to keep the CARI constant. The very compact design (16”X24”X16”) and the use of extensively proven components (witch ensure a minimal maintenance) make the CGA100 reliable and suitable for industrial process.

The CGA100 should be ideal equipment for use in automatic control system and provide a valuable service to many industrial users.
