ABSTRACT:
This invention relates to a device for measuring solids in a moving stream installed in a closed system in which the prevailing pressure therein is equal to or higher than the ambient pressure. The device includes an inlet which is smaller in cross-section than a main portion of the housing for providing a solid free internal volume vertically downwardly of the inlet. A diverter member rotatable about a horizontally disposed axis is disposed in the housing portion and has a length greater than the width of the housing so as to permit the upper edge of the diverter member to swing outside the flow of solids into the main portion of the housing while the lower edge of the diverter contacts the opposite wall of the housing for dividing the main portion of the housing into two spaces. The center of gravity of the diverter member is located above the axis of rotation so as to permit solids to fill one space between the diverter member and the housing until a weight of the solids material imparts an opposite rotary motion upon the diverter member for producing another space to be filled. Position sensing means is provided for signalling the position of the diverter member within the housing for indicating which space is being filled.
