摘要

Device for in - situ comparison of the seed meters with - and outflow test substance concentration measuring devices (7, 8) for separating degree measurement on separators (4) of impurities of a flowing fluid in a flow channel (1) with– a first a flowing fluid generating assembly (2),– a second the flowing fluid consist of a reagent assembly (3 227.),– the separator (4) in the flowing and with the reagent fluid enriched,– Measuring points (5, 6) for the concentration of the test substance in the flow direction upstream of the separator (4) and downstream of the separator (4),– a first valve assembly (10) in the flow paths of the measurement points (5, 6),– a dilution system (9) for a too high test substance concentration in a flow path,– a reference - dilution system (12) for the calibration of the dilution system (9) in the other flow path,– a second valve assembly (11) in the flow paths of the measurement points (5, 6),– the test substance concentration measuring devices (7, 8) for the fluid present in the flow paths and– a with the actuating devices of the valves of the valve assemblies (10, 11) interconnected control device,wherein said control means includes the flow paths between the measuring points (5, 6) of the test substance concentration and the test substance concentration measuring devices (7, 8) so switchable control device is that the test substance concentration measuring devices (7, 8) directly or via the dilution system (9) or via the reference - dilution system (12) either with the measuring points (5, 6) or together with only one of the measuring points (5, 6) for the test substance concentration and thus connected to one another are adjustable.
