Description
Anordnungen zum Messen von Volumen gefüllter Behälter sind bekannt. Die auf mechanischem Prinzip beruhenden Anordnungen ergeben die Schwierigkeit der Übertragung der Meßwerte vom Behälter auf das Ableseinstrument bei getrennter Aufstellung von Behälter und Ableseinstrument. Arrangements for measuring the volume of filled containers are known. The arrangements based on mechanical principle give rise to the difficulty of the Transfer of the measured values from the container to the reading instrument with separate installation of container and reading instrument.
Meßanordnungen, die auf dem Grundsatz der Durchstrahlung der im Behälter befindlichen Flüssigkeit aufgebaut sind und bei denen durch eine lichtempfindliche Zelle die Änderung des Ph6tostromes bei Änderung der Dicke der durchstrahlten Schicht gemessen wird, haben den Nachteil, dåß das Anzeigeinstrument dieser Anordnungen nur für eine Flüssigkeit bestimmter Lichtdurchlässigkeit geeicht werden kann und schon kleine Abweichungen von diesem Sollwert der Lichtdurchlässigkeit falsche Werte am Anzeigeinstrument verusachen. Measurement arrangements based on the principle of irradiation in the container located liquid are built up and where by a light-sensitive Cell shows the change in the ph6to current when the thickness of the irradiated layer changes is measured, have the disadvantage that the display instrument of these arrangements can only be calibrated for a liquid with a certain light transmission and even small deviations from this target value for light transmission are wrong values on the display instrument.
Die auf Kap aiitätsmes sung beruhenden Anordnungen ergeben ebenfalls unrichtige Werte am Anzeigeinstrument bei Änderungen der Diel ektrizitätskonstante der Flüssigkeit von demjenigen Wert, auf welchen das Anzeigeinstrument geeicht worden ist. The arrangements based on capacity measurement also result Incorrect values on the display instrument when the dielectric constant changes the liquid of the value to which the indicating instrument has been calibrated is.
Diese Nachteile sollen erfindungsgemäß wie folgt behoben werden: Die Zeichnung zeigt schematisch einen Teil eines Behälters im Schnitt; ein fest in BehälteroberseiteI angeordneter Strahler 2 sendet durch eine Sammellinse 3 ein parallel gerichtetes Strahlenbündel 4 unter einem konstanten Winkel b auf den ebenen Spiegel 6, der das Strahlenbündel 4 reflektiert, Strahlenbündel 5, und auf den Empfänger 7 wirft. Der Empfänger 7 ist eine Photozelle, deren Strom bei Belichtung, oder bei einer Sperrschichtphotozelle der durchgelassene Fremdstrom, unmittelbar oder verstärkt in bekannter Weise auf ein Anzeigeinstrument 8 gegeben wird. According to the invention, these disadvantages are to be eliminated as follows: The drawing shows schematically a part of a container in section; a feast Radiator 2 arranged in the upper side of the container sends in through a converging lens 3 parallel beam 4 at a constant angle b on the flat Mirror 6, which reflects the bundle of rays 4, bundle of rays 5, and onto the receiver 7 throws. The receiver 7 is a photocell whose current when exposed, or when a barrier photocell, the external current that has passed through, direct or amplified is given to a display instrument 8 in a known manner.
Bei Eichung des Anzeigeinstruments in Volumeneinheiten zeigt das Anzeigeirpstrument direkt das Volumen der im Behälter noch befindlichen Flüssigkeit an. Der Spiegel 6 ist auf einem Schwimmer g befestigt und bewegt sich in seiner Firung Io so, daß der Sinus des Winkels a, gebildet durch die Strahlenbündel 4 und 5, gleich ist dem Produkt aus der Mittenentfernung ffi zwischen Sender 2 und Empfänger 7 und dem Sinus des für die jeweilige Anordnung konstanten Winkels b,gebildet durch das Strahlenbündel 4 und die Verbindungslinie zwischen dem Sender 2 und Empfänger 7, der Strecken, dividiert durch die Länger des refiek tierten Strahlenbündels 5; als Formel geschrieben also: sin a= m sin ; die Ebene des Spiegels steht also immer senkrecht auf der Winkelhalbierenden des Winkels a Der für die jeweilige Anordnung konstante Winkel b liegt zwischen den Grenzen größer als Oo und kleiner als I800, also o°<b<X#o°, 1iOO, je nach den Bedillgurlgen des betreffenden Behälters. Durch die Ausbildung der Führung 10 des Spiegels 6 nach dieser mathematisch eindeutig festgelegten Kurve wird erreicht, daß bei der Auf- und Abwärtsbewegung des Spiegels 6, bedingt durch die verschieden hohe Füllung 'des Behälters, der Spiegel 6 immer so steht, daß das reflektierte Strahlenbündel 5 immer auf den Empfänger trifft.When calibrating the indicating instrument in volume units, the indicating instrument shows directly indicates the volume of the liquid still in the container. The mirror 6 is attached to a float g and moves in its firung Io so that the sine of the angle a, formed by the bundles of rays 4 and 5, is equal to this Product of the center-to-center distance ffi between transmitter 2 and receiver 7 and the sine of the angle b, which is constant for the respective arrangement, formed by the bundle of rays 4 and the connecting line between the transmitter 2 and receiver 7, the routes, divided by the length of the reflected beam 5; written as a formula thus: sin a = m sin; the plane of the mirror is always perpendicular to the bisector of the angle a The angle b, which is constant for the respective arrangement, lies between the limits greater than Oo and less than I800, i.e. o ° <b <X # o °, 1iOO, depending on the Bedillgurlgen of the container in question. By training leadership 10 of the mirror 6 according to this mathematically clearly defined curve is achieved that in the upward and downward movement of the mirror 6, due to the different high filling 'of the container, the mirror 6 is always so that the reflected Beam 5 always hits the receiver.
Der Spiegel 6 ist in an sich bekannter Weise aus metallischem oder auch nichtmetallischem Werkstoff aust,Ceführt, je nach der Art der Füllung des Behälters; seine reflektierende Seite wird zweckmäß-igerweise in bekannter Weise mit einer Flüssigkeit abweisenden Schicht versehen. The mirror 6 is made of metallic or in a manner known per se also made of non-metallic material, depending on the type of filling of the container; its reflective side is expediently in a known manner with a Liquid-repellent layer provided.
Der Sender 2 emittiert kurz-, mittel- oder langwelliges Licht mono- oder panchromatischer Art und ist als Punkt- oder Linienstrahler ausgebildet. je nach den Erfordernissen. Der Sender 2 mit dem Empfänger 7 und dem Spiegel 6 mit Schwimmer 9 und der Spiegelführung I0 können auf einem gez meinsamen Teil I befestigt werden, das gleichzeitig als Deckel für den Behälter dient. The transmitter 2 emits short-, medium- or long-wave light mono- or panchromatic type and is designed as a point or line source. ever according to the requirements. The transmitter 2 with the receiver 7 and the mirror 6 with Float 9 and the mirror guide I0 can be attached to a common part I. that also serves as a lid for the container.
