PCME QAL 182 WS

QAL1 approved ProScatterTM particulate CEM for the extractive sampling and measurement of particulate in saturated wet gas streams

Continuous Particulate Monitoring for saturated wet stack applications typically found after wet scrubbers, wet electrostatic precipitators and wet flue gas desulphurization plant.

QAL1 certified against EN 15267-3 to meet EN 14181 and other International standards.

The PCME QAL 182 WS is suitable for measuring particulate emissions from wet scrubbers and other processes where the flue gas falls below dew point (cold stack conditions) or water droplets are present. The extractive instrument takes a representative continuous sample from the stack, heats this well above dew point to evaporate water droplets and then measures the particulate concentration under dry conditions. This extractive approach with heating overcomes the problems of interference from condensation and water droplets associated with using in-situ particulate monitors after wet collectors.

The PCME QAL 182 WS uses an advanced ProScatter™ forward light scatter sensor which is certified by TUV and MCERTS as QAL1 compliant. With certification ranges covering both 0-15mg/m³ and 0-100mg/m³, the sensor is suitable for monitoring the highly abated emissions found after Flue Gas Desulphurization plant (FGD). The instrument is able to monitor saturated flue gas which is critical for the application of monitoring emissions from a coal fired power plant fitted with a wet FGD system and meets the requirements of PS-11 and EN 14181.
