This technical data sheet describes one example of the system. The GASMET CEMS is used for on-line measurements. It is an ideal tool to use for measuring trace concentrations of pollutants in wet, corrosive gas streams. All parts of the GASMET CEMS can be heated up to 180 ºC. It can be used for undiluted gases and the sample gases do not need drying beforehand. The GASMET CEMS consists of GASMET FTIR Gas Analyzer, GASMET PC, GASMET Sampling System. As an option the system can be equipped with GASMET Oxygen analyser and/or with total hydrocarbon analyser (FID). All parts of the system are 19” rack mounted and are installed on the pull-out shelves. The GASMET CEMS includes all power connections and temperature controllers for heated lines and heated sample probe. The operation of the system is fully automatic and controlled by the Calcmet software. Additionally all functions of the GASMET CEMS can also be used manually. GASMET PC and Calcmet application software controls the CEMS. The measuring data can be transferred from the PC to the Control room with digital outputs (ModBus) or with analog outputs 4-20 mA. The alarms are transferred with relay contact. The GASMET CEMS provides different alarm functions such as Function alarm, Service alarm and System alarm. Function and service alarms are associated with the GASMET FTIR Gas Analyzer and with the Calcmet analysis software. A system alarm comes from GASMET Sampling System and it includes temperature alarms (from sample probe, heated lines, sampling unit), flow alarm and pressure alarm for zero gas. If any of the critical alarms is activated, instrument air starts to flow automatically into the system to prevent condensation. Standard CEMS is also equipped with a one span gas valve to allow automated span checks as required by the new legislation. GASMET CEMS is air conditioned with a compressor-cooling unit on top of the cabin. Optionally cooling unit can be mounted on side of the cabin. Additional features of the GASMET CEMS includes multipoint sampling for two sample points and gas inlets for additional span gases. GASMET CEMS is also supported by full remote control.
