  • BAM (Beta Attenuation Mass Monitor)
    The BAM (Beta Attenuation Mass Monitor) measures particulate concentrations automatically. The mass density is measured using the technique of Beta attenuation. A small Beta source is coupled to a sensitive detector which counts the Beta particles. As the mass of particles increases the Beta count is reduced. The relationship between the decrease in count and the particulate mass is computed according to a known equation (the Beer-Lambert law).
