  • Patent number: 6790367
    Abstract: A method and an apparatus for separating and measuring solids from multi-phase well fluids. The apparatus comprises a separator; an upper solids level and a lower solids level sensor, both connected to the separator; a dump valve operatively connected to the separator; and a control module operatively connected to the dump valve to move the dump valve between an open and a closed position. The upper solids level sensor generates a first signal when the upper level of accumulated solids-within the separator reaches a pre-determined upper level. The lower solids level sensor generates a second signal when the upper level of accumulated solids within the separator reaches a predetermined lower level. The control module receives the first and second generated signals such that upon receipt of the first signal the control module causes the dump valve to open and upon receipt of the second signal the control module causes the dump valve to close.
