The FWE200DH dust measuring device is designed to continuously measure dust concentrations in wet gases. The gas is extracted via a gas sampling probe and heated above the dew point. Droplets in the gas vaporize, making it impossible for them to falsify the measurement results. The very sensitive scattered light measurement principle enables accurate measurements even at low dust concentrations. The FWE200DH meets the requirements of EN 14181 and EN 15267.
Monitoring of wet gas scrubbing facilities
Meassurement in very wet exhaust air and in technological processes
Measurement in wet gas downstream of desulfurization plants
Device properties:
For very low to medium dust concentrations
Gas sampling and return combined in one probe
Contamination check
Automatic monitoring of zero and reference point
Integrated system diagnostics for early detection of maintenance requirements
Benefits
Reliable and proven dust measurement in wet gases
Economic operation due to very few consumable parts and very low installation effort
Very low maintenance since no moving parts come into contact with the aggressive gas
