Description
Meßgerät zum Bestimmen der Konzentration von Schwebstoffteichen in Flüssigkeiten, insbesondere von Sandkonzentrationen in fließenden Gewässern Die Erfindung betrifft ein Meßgerät zum Bestimmen der Konzentration von Schwebstoffteilchen in Flüssigkeiten, insbesondere von Sandkonzentrationen in fließenden Gewässern, bei dem die das Gerät durchströmende, die Schwebstoffe enthaltende Flftss igkeit und eine Vergleichs flüssigkeit getrennt mit radioaktiven Strahlen durchstrahlt, die durch die Flüssigkeiten geschwächsten Strahlen gemessen werden und die Differenz der so erhaltenen Meßwerte zur Bestimmung der Konzentration herangezogen wird.Measuring device for determining the concentration of suspended matter ponds in Liquids, especially of sand concentrations in flowing water The The invention relates to a measuring device for determining the concentration of suspended matter in liquids, especially of sand concentrations in flowing waters, in which the liquid containing suspended matter flowing through the device and irradiate a comparison liquid separately with radioactive rays, the rays weakened by the fluids are measured and the difference the measured values obtained in this way are used to determine the concentration.
Ein bekanntes Gerät dieser Bauart weist eine Durchfltißkammer und eine abgeschlossene, mit destilliertem Wasser gefüllte Vcrgleichskamrner auf (International Journal of Applied Radiation and IsotopeEs 1967, Vol. 18, pp. 585 - 593, Pergamon Press Ltd.). tJber den Kammern ist ein gemeinsamer Proportionalzähler angeordnet, dem eine schwenkbare Stralllungsquelle zugeordnet ist, die wahlweise unter die Durchlußkammer und unter die Vergleichskammer geschwenkt werden kann. Dabei wird die Strahlung in der Durchflußkammer stärker geschwächt als in der Vergleichskammer, sofern erstere Schwebstoffteilchen ent11tilt, so daß ein Differenzsignal gebildet werden kann.A known device of this type has a flow chamber and a closed comparison chamber filled with distilled water (International Journal of Applied Radiation and IsotopeEs 1967, Vol. 18, pp. 585-593, Pergamon Press Ltd.). A common proportional counter is arranged above the chambers, which is assigned a pivotable radiation source, which is optionally under the flow chamber and under the comparison chamber can be pivoted. It will the radiation in the flow chamber is weakened more than in the comparison chamber, if the former contains suspended matter, so that a difference signal is formed can be.
Ausgehend von diesem Stand der Technik hat die vorliegende Erfindung zur Aufgabe, die Genauigkeit der Differenzmessung zu erhöhen.The present invention is based on this prior art the task of increasing the accuracy of the differential measurement.
Zur Lösung dieser Aufgabe wird erfindungsgeinäß vorgeschlagen, den die Vergleichsflüssigkeit aufnehmenden Teil des Geräts als Durchflußkammer auszubilden und wenigstens auf der Einströmseite mit einem die Schwebstoffe zurückhaltenden Filter zu begrenzen. Dadurch liegt an der Vergleichsnießstrecke mit Ausnahme der durch das Sieb eliminierten Schwebstoffteilchen dieselbe Wasserqualität vor wie an der Meßstrecke fiir das ungefilterte Wasser, d. h. Dichteänderungen des Wassers infolge von gelösten Stoffen oder Temperaturschwankungen werden bei der Messung vollstandig ausgeschaltet.To solve this problem, it is proposed according to the invention, the the comparison liquid receiving part of the device to be designed as a flow chamber and at least on the inflow side with one that retains the suspended matter Limit filter. This is due to the comparison usufruct with the exception of the suspended particles eliminated through the sieve have the same water quality as at the measuring section for the unfiltered water, d. H. Changes in density of water as a result of dissolved substances or temperature fluctuations are during the measurement completely switched off.
Nach einer vorteilhaften Weiterbildung der Erfindung sind zwei gleichartige Strahlungsquellen auf gleicher Höhe entlang einer gemeinsamen Trennwand zwischen den beiden MeBbereichen angeordnet. Diesen Strahlungsquellen sind Detektoren zugeordnet, die jeweils an der Peripherie der MeBbereiche befestigt sind.According to an advantageous development of the invention, two are similar Radiation sources at the same height along a common partition between arranged in the two measuring areas. Detectors are assigned to these radiation sources, which are each attached to the periphery of the measurement areas.
Auf diese Weise kann die Differenz messung kontinuierlich- bei hoher Nachweisempfindlichkeit durchgeführt werden. Außerdem werden dadurch bewegliche Bauteile vermieden.In this way, the difference can be measured continuously - at high Detection sensitivity can be carried out. It also makes them movable Components avoided.
Ein Ausführungsbeispid der Erfindung wird anhand einer schematischen Zeichnung erläutert: Durch den Meßbereich 1 strömt quer zur Meßstrecke z die die Schwebstoffe enthaltende Flüssigkeit. Der von der Vergleichsflüssigkeit durchströmte Meßbereich 3 mit der Meßstrecke 4 wird von Filtern 5, 6 und von dem Strahlergehäuse 8 und Detektorgehäuse 9, sowie von Kammerwänden 2 begrenzt. Beide Meßbereiche sind durch das Teil 8 voneinander getrennt, das auch die beiden Strahler 10, 11 enthält. An die beiden Meßstrecken 2, 4 schließen sich nach außen die Strahleneintritts£enster 12, 13 der Szintillatinnszähler ;4, 15 an. Die Szintillationszähler und die Strahler 10, 11 sind durch Halterungen 16, 17 und 48,die z.B. als Strömungsleitwände ausgebildet sein können, gegeneinander fixiert. Auch das Strahlergehäuse 8 und die Detektorengehäuse 9, 91 können mit Strömungsleitwänden verkleidet sein. Das Auswertegerit 19 befindet sich oberhalb der Wasseroberfläche 20 und ist mit den Detektoren über elektrische Zuleitungen 21 verbunden.An embodiment of the invention is based on a schematic Drawing explained: The flows through the measuring area 1 transversely to the measuring section z Liquid containing suspended solids. The liquid flowing through it Measuring range 3 with the measuring section 4 is of filters 5, 6 and of the radiator housing 8 and detector housing 9, as well as bounded by chamber walls 2. Both measuring ranges are separated by part 8 separated, which also contains the two radiators 10, 11. To the two measuring sections 2, 4, the radiation entry windows 12, 13 of the scintillate counters close to the outside ; 4, 15 at. The scintillation counters and the emitters 10, 11 are by brackets 16, 17 and 48, which can be designed as flow guide walls, for example, against each other fixed. The emitter housing 8 and the detector housing 9, 91 can also have flow guide walls be disguised. The evaluation unit 19 is located above the water surface 20 and is connected to the detectors via electrical leads 21.
