Abstract

A hose leveller with an electrical levelling indicator is designed for use with two fluid containers (1) connected by a hose. The device avoids operator errors and difficulties associated with visual comparison methods, partic. where determination of height difference is required. It also eliminates the complicated setting up of contact probe balancers which also have a tendency to lose fluid during use. Both containers are hermetically sealed press chambers with an associated pressure detector. The containers and the connecting hose are completely filed with fluid. When the containers are at the same height the press indicators give the same output signal. A height difference produces a corresp. signal difference. The signals are evaluated and compared in an electronic measurement and amplifier circuit connected to an electrical indicator.

Description

Schlauchwaage mit elektrischer Niveauanzeiqe Hose level with electrical level indicator

Die Erfindung betrifft eine Schlauchwaage mit elektrischer Niveauanzeige zweier Flüssigkeitsgefäße, welche mit einem schlauch kommunizierend verbunden sind. The invention relates to a hose balance with an electrical level indicator two liquid vessels, which are connected with a hose communicating.

Die Schlauchwaagen üblicher Bauart bestehen im wesentlichen aus zwei, mittels eines Schlauches kommunlzlerend verbundenen, transparenten MeProhren, aus Glas oder Plexiglas, in welchen der Stand des Fliissiqkeitsspiegels gegenüber einer Marke oder Skala beobachtet werden kann; Dis Messen mit dieser Ausführung einer Schlauchwaage ist relativ umständlich, da beim Vergleich der Fltisstgkeitsspiegel in den beiden Meßrohr, der Flüssigkeitsspiegel in dem bezuggebenden Meßrohr sich ständig ändert, wenn der Fl(issigkeitsspiegel im bezugnehmenden Meßrohr auf die Bezugshöhe abgeglichen wird. The hose levels of the usual design essentially consist of two, transparent measuring tubes connected for communication purposes by means of a hose Glass or Plexiglas, in which the level of the liquid level compared to a Mark or scale can be observed; Dis measure with this execution one Hose level is relatively cumbersome, since when comparing the liquid level in the two measuring tubes, the liquid level in the referring measuring tube constantly changes when the liquid level in the referring measuring tube reaches the Reference height is adjusted.

Oft entstehen auch Fehler und Irrtümer beim Ablesen des Flüssigkeitsstahdes über die Skala am Meßrohr, sowie beim Umrechnen der angezeigten Werte, insbesondere beim Festlegen bestimmter Höhendifferenzen.Errors and mistakes often arise when reading the liquid level using the scale on the measuring tube, as well as when converting the displayed values, in particular when defining certain height differences.

Weiters hat man Schlauchwaagen entwickelt, welche in den Meßrohren meßbar verstellbare, mit dem Flüssigkeitsspiegel in Berührung zu bringende Spitzen aufweisen, welche beim Berühren des Flüssigkeitsqlegels daher die in den kommunizierenden Gefäßen befindliche, elektrisch leitfähige Flüssigkeit einen Stromkreis schließen, welcher ein optisches oder akustisches Signal auslöst. Furthermore, hose balances have been developed which are located in the measuring tubes measurably adjustable tips to be brought into contact with the liquid level have which when touching the liquid quell therefore the communicating in the Electrically conductive liquid in vessels close a circuit, which triggers an optical or acoustic signal.

Diese Art von Schlauchwaagen ergibt eine hohe Meßgenauigkeit, ist aber durch die Einstellarbeiten sehr umständlich in der Anwendung.This type of hose level results in a high level of measurement accuracy but very cumbersome to use due to the adjustment work.

Außerdem ist es störend, daß die Flüssigkeit bei der Anvendunq oft durch die nach oben offenen Meßrohre austritt, und somit ein Fliissigkeitsveiust eintritt. In addition, it is annoying that the liquid is often used when it is used exits through the measuring tubes, which are open at the top, and thus a liquid cone entry.

Aufgabe dieser Erfindung ist es, die vorstehend geschilderten Nachteile bekannter Bauarten zu vermeiden,insbesondere was die Bedienung betrifft, d.h. eine Schlauchwaage zu schaffen, bei der sich die Flüssigkeit in einem geschlossenen System befindet, und der ivauunterschied bzw. die Niveaugleichheit zweier Flüssigkeitsgef8ße ständig, selbständig und automatisch gemessen, und verglichen wird, um den absoluten Betrag der Niveauunterschiede zu erhalten, welcher an einem eigenen Anzeigegerät zur Anzeige gebracht wird. The object of this invention is to overcome the disadvantages outlined above of known designs, especially when it comes to operation, i.e. a To create hose level in which the liquid is in a closed system and the difference in level or the same level of two liquid vessels constantly, independently and automatically measured and compared to the absolute The amount of level differences to be obtained on a dedicated display device is brought to the display.

Erfindungsgemäß wird dies dadurch erreicht, daß die beiden Flüssigkeitsgefäße als hermetisch abgeschlossene Druckgefäße ausgebildet sind, daß an den beiden Druckgefäßen jeweils ein elektrischer Druckaufnehmer angebracht ist, daß das gesamte System (die beiden Druckgefäße inklusive des Schlauches) vollständig mit Flüssigkeit gefüllt ist, daß die, den unterschiedlichen bzw. gleichen Niveau der beiden Druckgefäße und dom daraus resultierenden unterschiedlichen bzw. gleichen Druck, entsprechenden Ausgangssignale der beiden elektrischen Druckaufnehmer, einem gemeinsamen Meß- und VerstSrkerelektronlkgerät zum Vergleichen und Auswerten zugeführt werden, unddaß das Gerät an ein' elektrisches Anzeigegerät zur Anzeige angeschlossen ist. According to the invention this is achieved in that the two liquid vessels are designed as hermetically sealed pressure vessels that on the two pressure vessels an electrical pressure transducer is attached in each case that the entire system (the both pressure vessels including the hose) are completely filled with liquid is that the, the different or the same level of the two pressure vessels and dom resulting different or same pressure, corresponding Output signals of the two electrical pressure sensors, a common measuring and Amplifier electronics are supplied for comparison and evaluation, and that the device to an 'electrical display device connected for display is.

Merkmale und Einzelheiten dieser Schlauchwaage werden an Hand der Zeichnung, welche ein Ausführungsbelspiel der Erfindung in schematischer Darstellung zeigt, aufgefihrt. Features and details of this hose leveler are shown on the basis of the Drawing showing an embodiment of the invention in a schematic representation shows, listed.

Mit 1 sind die beiden Druckgefäße gekennzeicslnet, welche mit einem Schlauch 5 kommunizierend verbunden sind. Auf der Oberseite der Druckgefäße 1 ist jeweils ein elektrischer Druckaufnehmer 4 anqebracht, der über elektrischeAnschlußleitungen 6 an die in einem Gerät 7 integrierte gemeinsame Meß- und Verstärkerelektronik angeschlossen ist. The two pressure vessels are marked with 1, which are marked with a Hose 5 are connected in a communicating manner. On top of the pressure vessels 1 is in each case an electrical pressure transducer 4 is attached, which is connected via electrical connecting lines 6 connected to the common measurement and amplifier electronics integrated in a device 7 is.

Der Meßvorgang mit dem erfindungsgemäßen Gerät erfolgt in der Weise, daß die beiden Druckgef0ße 1 mittels der an ihnen angebrachten Markierungen 2 auf gleiches Niveau 3 eingestellt waren, wohei durch das Anzeigegerät 8, welches von dem Meß- und Verstärkerelektronik-Gerät 7 angesteuert wird, eine 0- bzw. Mittenanzeige erfolgt, bzw. darauf abgeglichen wird. The measuring process with the device according to the invention is carried out in the manner that the two pressure vessels 1 by means of the markings 2 attached to them same level 3 were set, namely by the display device 8, which of the measuring and amplifier electronics device 7 is controlled, a 0 or center display takes place or is compared to it.

Werden nun die beiden Druckgefäße 1 an die beide! tellen des Prüfobjektes, dessen Höhendifferenz festgestellt und ausgeglichen werden soll, gebracht, so wird vorerst die Markierung 2 eines Druckgefäßes auf die Bezugshöhe eingestellt und das andere Druckgefäß unter Beobachtung des Anzeigegerätes 8, welches nun die Niveauunterschiede der beiden Druckgefäße 1 anzeit, soweit verschoben, bis durch das Anzeigeerät 8 eine 0- bzw. eine itenanzeige erfolgt, was bedeutet, daß die beiden Druckgefäße 1 bzw. Now the two pressure vessels 1 are attached to the two! locations of the test object, whose height difference is to be determined and compensated, brought, so is first set the marking 2 of a pressure vessel to the reference height and that other pressure vessel while observing the display device 8, which is now the level differences of the two pressure vessels 1, shifted until indicated by the display device 8 a 0 or an ite display occurs, which means that the two pressure vessels 1 or

die rtarkierungen 2 gleiches Niveau haben. Es genügt somit, beim Menvorgang, nur auf das Anzeigegerät 8 zu achten.the marks 2 have the same level. It is therefore sufficient, during the menu process, just pay attention to the display device 8.
