Description

Strömungsmesser mit umlaufendem Schwimmer Die Erfindung betrifft einen Strömungsmesser für gasförmige oder flüssige Stoffe mit einem durch die Strömung in Umdrehung versetzten Schwimmer und besteht im wesentlichen darin, daß der Schwimmer den Rotor eines elektrischen Generators bildet und die induzierten Ströme die Schwimmerstellung oder die Schwimmerdrehzahl angeben.Flow meter with rotating float The invention relates to a Flow meter for gaseous or liquid substances with a through flow rotated float and consists essentially in the fact that the float forms the rotor of an electrical generator and the induced currents the float position or specify the float speed.

Bei derartigen Strömungsmessern versetzt man den Schwimmer in Umdrehung, indem man entweder den Strom auf schräg zur Strömungsrichtung verlaufende Flächen wirken läßt, oder indem man dem Strom selbst eine Drehrichtung erteilt. Bei frei schwebenden und infolgedessen reibungslos arbeitenden Schwimmern oder Schwebekörpern genügen, namentlich bei hohen Strömungsgeschwindigkeiten, geringe Kräfte zur Er zielung schneller Umdrehungen. .With such flow meters, the float is set in rotation, either by directing the current on surfaces that are inclined to the direction of flow can act, or by giving the current itself a direction of rotation. At free floating and consequently smoothly working floats or floats It is sufficient, especially at high flow velocities, to use small forces to generate it aiming for faster revolutions. .

Bei einem Ausführungsbeispiel des Erfindungsgedankens ist der Schwimmer mit einem oder mehreren permanenten Magneten versehen. Längs des Schwimmerrohres sind Spulen mit oder ohne Eisenkern angeordnet, in denen von dem Schwimmer Ströme induziert werden. Der Schwimmer bildet also gewissermaßen den Rotor, und das Rohr, in dem er sich bewegt oder eine Stange, die er umfaßt, den Stator eines elektrischen Generators. Aus praktischen Gründen wird der durch den Schwimmer verursachte Kraftverlust immer möglichst niedrig zu halten sein und infolgedessen werden auch die entstehenden Ströme nur ganz gering sein können, so daß sie verstärkt werden müssen, um der Anzeige oder Regelung der Strömung dienen zu können.In one embodiment of the inventive concept, the float is provided with one or more permanent magnets. Along the float tube are arranged coils with or without an iron core, in which currents from the float be induced. The float forms the rotor, so to speak, and the tube, in which it moves, or a rod which it embraces, the stator of an electrical one Generator. For practical reasons, the loss of strength caused by the swimmer must always be kept as low as possible and consequently the resulting The currents can only be very small, so that they have to be amplified in order to make the display or to control the flow.

Der Erfindungsgedanke läßt sich, je nach den im einzelnen vorliegenden Aufgaben, vielseitig ausgestalten. So kann beispielsweise das Meßrohr mit einer größeren Zahl von Spulen ausgestattet werden, von denen jeweils die in derselben Höhenlage angeordneten zusammen mit dem Schwimmer den Generator bilden. Oder es können Spulen nur in einer Grenzlage oder in zwei Grenzlagen des Schwimmers angeordnet sein. Ferner kann der beispielsweise kreiselförmig ausgebildete Schwimmer in seinem oberen und in seinem unteren Teil je eine zur Induktion geeignete Zone haben.The idea of the invention can be, depending on the present in the individual Tasks, varied. For example, the measuring tube with a larger number of coils are fitted, each of which is in the same Altitude arranged together with the float form the generator. Or it Coils can only be arranged in one limit position or in two limit positions of the float be. Furthermore, the float, which is configured in the shape of a gyroscope, can be in his upper and lower part each have a zone suitable for induction.

Nicht nur die jeweilige Höhenlage des Schwimmers, sondern auch seine Drehgeschwindigkeit kann als Mittel für die Anzeige oder Regelung benutzt werden, insbesondere wenn man den Schwimmer als mehrpoligen Anker ausbildet. Um den Luftspalt zwischen dem Schwimmer und dem Statorsystem zu verkleinern, kann man den Schwimmer mit Fliehstücken versehen, die den Zwischenraum zwischen Rotor und Stator verkleinern..Not only the respective altitude of the swimmer, but also his Rotational speed can be used as a means for display or regulation, especially if you train the swimmer as a multi-pole anchor. Around the air gap To zoom out between the float and the stator system, you can use the float provided with fleece pieces that reduce the gap between rotor and stator ..
