Gravimetric dust measuring devices
Gravimetric dust measurement devices extract a partial gas flow from the duct under predefined conditions and use a filter to separate out the dust particles. The amount of dust is ascertained by weighing the filter. The differential pressure is measured to determine the extracted volume. These two values are then used to calculate the concentration of dust in the duct with a high level of accuracy. Gravimetric dust measurement is ideal for calibrating other dust measuring devices and for taking the kinds of comparative measurements that are required by the relevant authorities.
