PCME QAL 991Particulate Monitoring System
The PCME QAL 991 is an approved Particulate CEM (Continuous Emission Monitor) designed to meet and exceed CEN standard EN 14181 / EN 13284-2
The instrument design permits up to 32 sensors to be connected to a
single central control unit. The control unit provides power for the
sensors and industry standard outputs are provided for easy connection
to plant control systems.
Highly Accurate Emissions Data The instrument’s automatic self-checks are extended to provide
zero, span and contamination tests which assess uncertainty and to
record results for later statistical analysis. This provides the
infrastructure for QAL3 tests according to EN-14181.
Satisfy QAL3 Requirements Optional PC software ‘QAL Reporter’ provides secure emissions and
QAL3 reporting. It includes the statistical treatment of the zero and span
results for the user to demonstrate that the instrument is operating
according to defined specifications (uncertainty).
KEYBENEFITS
• Unaffected by contamination on the
sensor rod
• On-board Calculation and display of
the BTU index (gas calorific value, only
with syngas analysers)
• The results of the automatic upscale
(span) check can optionally be used
to compensate for the effects of any
contamination
• System self-checks, with logging of
Zero and Span check data for QAL3
reporting
