Abstract

A method and arrangement for flow measurement of fluids and gases are partic. suitable for use in the indication of instantaneous fuel flow in powered vehicles to enable an economical driving method to be adopted. The fluid or gas flows past and rotates a toothed wheel (U) whose teeth (Z) interrupt a light beam emitted from a light source (Q) and received by a photo-electric element (P). The resulting pulsed photo-electric element output signal is converted by a circuit (DU) into a rate of revolution or flow rate signal which is displayed on a meter (M). The wheel is contained in a sealed chamber (G) with input and output flow ports and transparent windows (F) for the light beam.

Description

VERFAHREN UND VORRICHTUNG ZUR DURCHFLUSSMESSUNGMETHOD AND DEVICE FOR FLOW MEASUREMENT

=============================================== Die Erfindung betrifft ein Verfahren und Verrichtung zur Durchflußressung ven Flüssigkeiten und Gasen. Bei dieser Methode ist es möglieh, jedem Benutzer dieser Einrichtung eins genaue Ablesung der momentan durchfließender eder durchströmender Menge von Flüssigkeit oder Gas. Diese Aufgabe wird erfindungsmäsig dadurch gelöst, daß sie fließenden oder strömenden Medien eine radiale Drehung eines verzahnten Umlaufrades in einer Kammer herverrufen. Die Verzahnung unterbricht dabei einen Lichtstrahl, der von einen Fetoelement aufgenommen und zur elektronischen Steuerung, Regelung oder Anzeige benutst wird0 Die Erfindung ermöglicht durch Beebachten und/oder Sichtkontrelle eines Neßinstrunente eine sparbewußte Fahrtweise mit PKW, LKW und sonstigen Transpertmitteln und ermöglicht daher Brennstoff- und Kestenersparnis, was mit Hinsicht auf ständig drohende Ölknappheit von Bedeutung seien könnte.=============================================== The invention relates a method and device for the flow pressure of liquids and gases. With this method it is possible to provide an exact one for each user of this facility Reading of the currently flowing through or through flowing amount of liquid or gas. This object is achieved according to the invention in that they flow or flowing media a radial rotation of a toothed planetary gear in a Call the Chamber. The toothing interrupts a light beam from a Fetoelement added and for electronic control, regulation or display benutst wird0 The invention is made possible by observation and / or visual control a Neßinstrunente a saving-conscious way of driving with cars, trucks and other means of transport and therefore enables fuel and box savings, what with regard to constantly impending oil shortages could be significant.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher besohrieben Im Gehäuse G ist das verzahnte Umlaufrad U das undurchsichtigem Material) axial in Körnern K gelagert. Beim Durchfluß von Flüssigkeit der Gas fängt das Umlaufrad an sich zu drehen. Das verursacht eine von Durchflußmenge (oder vom Gasdruck) abhängige und sich wiederholende Unterbreehung eines Lichtstrahles, der aus der Liohtquelle q durch durchsichtige, wasser- und gasdiehte Fensterchen F im Gehäuse vem Fetoelement P (Fetodiode, Fototransister usw.) aufgenommen wird0 Der zerhackte Lichtstrahl dient zur Steuerung eines Drehzahlumwandlers DU , dessen Meßinstrument M die Durchflußmenge anzeigt, die dem Durchfluß oder Gasdruck propertienal ist. An embodiment of the invention is shown in the drawing and is described in more detail below. In the housing G is the toothed planetary gear U the opaque material) stored axially in grains K. With the flow of Liquid or gas begins to turn the impeller. That causes one of Flow rate (or gas pressure) dependent and repetitive interruption of a light beam emerging from the Liohtquelle q through transparent, water and Small gas-tight window F in the housing vem Fetoelement P (fetodiode, phototransister etc.) is recorded 0 The chopped light beam is used to control a speed converter DU, whose measuring instrument M shows the flow rate, which corresponds to the flow rate or gas pressure is propertienal.
