Abstract
The invention relates to a sample flow control member to be used particularly in a continuously operated analysis of liquid or slurry-like materials, said control member being provided with members for selectively conducting the sample flow to an analyser. According to the invention, the control member (1, 21, 41) is installed in an essentially horizontal position and provided with at least one moving member (11, 28, 42) in order to turn the control member (1, 21, 41) around its rotation axis (12, 29, 48) in order to selectively conduct the sample flow to at least one analyser (7, 27; 44, 46) through at least one aperture (5, 25, 49) provided in the wall of the control member (1, 21, 41).
Claims13
A device for substantially continuously sampling liquid or slurry material, said device including a tubular member having a peripheral wall, first and second opposite ends spaced apart along a longitudinal axis, the tubular member being disposed with the longitudinal axis substantially horizontal for receiving the material to be sampled at said first end, having a first aperture in its peripheral wall, between the first and second ends, and having a second aperture angularly spaced from the first aperture about the longitudinal axis of the tubular member and positioned such that the first aperture is axially between the second aperture and the first end, and the device further including a means for turning the tubular member about its longitudinal axis selectively to either a first position, in which the first aperture is down and liquid or slurry material in the tubular member passes through the first aperture under gravity, and a second position, in which the second aperture is down and liquid or slurry material in the tubular member bypasses the first aperture and passes through the second aperture under gravity.
