FWE200
 
 
Dust monitor for wet gases
The FWE200 is designed to measure dust concentrations in saturated flue gas using the scattered-light measuring principle. The gas is withdrawn via an extraction probe. Any droplets are vaporized and, therefore, cannot falsify the result of the measurement.
Applications
Measuring dust concentrations, e.g. in saturated gas downstream of desulfurization plants; downstream of wet scrubbing plants, e.g. in waste incinerators; in wet exhaust gas from industrial processes.
