| Zusammenfassung: | A black powder detector comprises a flow cell or a flow-line bypass configured to attached to a flow-line, the flow cell or the flow-line bypass comprising a flow inlet and a flow outlet; an optical signal source positioned at a first side of the flow cell or the flow-line bypass, wherein the optical signal source is configured to emit an optical signal through the first side of the flow cell or the flow-line bypass; a first optical detector positioned at a second side of the flow cell, wherein the second side is opposite the first side, and the first optical detector is configured to detect atransmitted-light intensity of the optical signal transmitted through the second side of the flow cell or the flow-line bypass; and a second optical detector positioned at a third side of the flow cell, wherein the third side is different than the first side and the second side, the second optical detector is configured to detect the scattered-light intensity of a scattered optical signal transmitted through the third si |
