𝘌𝘭𝘦𝘤𝘵𝘳𝘰𝘋𝘺𝘯𝘢𝘮𝘪𝘤™ QAL1 Approved Particulate CEM QAL 991
QAL1 approved particulate CEM providing high quality emission measurement for low dust concentrations from dry industrial processes including Baghouses and Cartridge Filters
The QAL 991 is an approved particulate CEM (Continuous Emission Monitor) designed to meet and exceed CEN standard EN 14181 / EN 13284-2. Particularly suited to monitoring emissions from industrial processes regulated under the European Waste Incineration Directive (WID) and Large Combustion Power Plant Directive (LCPD), the PCME QAL 991 is also proven in other industrial processes controlled with high efficiency bag filtration. The instrument holds QAL1 approval specified in EN 15267-3, under both MCERTS and TUV.
Features & Benefits
- Robust design unaffected by product build-up on the sensor rod
- No additional services such as air purge required, providing lower cost of ownership
- Simple maintenance no requirement for specialist service personnel
- Complies with standards EN 13284-2, EN 14181 and EN 15267-3 and applications with Emission Limit Values (ELVs) of 7.5 mg/m3 (Incineration) and 15 mg/m3 (co-incineration)
- Automatic recording of drift checks (zero and span) to satisfy QAL3 requirements
- Networking of sensor channels and providing multiple inputs for external devices such as temperature, pressure and 02 normalisation
Main applications
- Stacks after bag filters, cartridge filters, cyclones, electrostatic precipitators, no filtration
- Variable velocities within range 5 – 25 m/s (typical bag filter velocity ranges)
- Non-condensing / dry flue gases
Typical Applications:
- Incineration
- Metals (eg Steel/Aluminium)
- Minerals (eg Cement/Gypsum)
- Chemicals (eg Detergent/Carbon Black)
- Power Generation Plant (eg Coal/Biomass)
