Description

Verfahren zur Messung der Geschwindigkeit oder Menge von Wasser und Gasen und Dämpfen mittels Induktion Die Erfindung betrifft eine Anordnung für das Meßverfahren von Strömungsgeschwindigkeiten.Method of measuring the speed or amount of water and Gases and vapors by means of induction The invention relates to an arrangement for the Measuring method of flow velocities.

Die induktive Strömungsmessung ist bekannt für leitende Flüssigkeiten. Wenn die Leitfähigkeit nicht ausreichend ist, hat man sie bisher durch Salzen der Flüssigkeit oder ähnliche Maßnahmen vergrößert.Inductive flow measurement is known for conductive liquids. If the conductivity is not sufficient, it has so far been achieved by salting the Fluid or similar measure enlarged.

Die Strömungsmessung bei Dämpfen oder nicht leitenden Gasen mittels der induktiven Methode ist bisher nicht bekanntgeworden, da sie daran scheiterte, daß die Leitfähigkeit des strömenden Mediums zu gering ist. Zur Messung solcher nicht leitenden Strömungen hat man bereits ein anderes Verfahren angewendet, bei dem die Strömungsgeschwindigkeit durch Messung der Laufzeit von ionisierten Strömungsteilen bestimmt wird. Hierzu wird das strömende Medium impulsweise ionisiert und das Eintreffen der Ionisationsimpulse mittels Empfangselektroden festgestellt, die in einem festgelegten Abstand von der Ionisierungsstelle angeordnet sind. Zur genauen Messung der Laufzeit ist jedoch im Gegensatz zur induktiven Strömungsmessung ein relativ hoher apparativer Aufwand erforderlich.The flow measurement of vapors or non-conductive gases by means of the inductive method has not yet become known because it failed to that the conductivity of the flowing medium is too low. To measure such Another method has already been used for non-conductive currents the flow velocity by measuring the transit time of ionized flow parts is determined. For this purpose, the flowing medium is ionized in pulses and the arrival the ionization pulses are detected by means of receiving electrodes, which are fixed in a Distance from the ionization point are arranged. For precise measurement of the running time However, in contrast to inductive flow measurement, it is a relatively high level of apparatus Effort required.

Erfindungsgemäß wird auch die Messung von nicht leitenden Flüssigkeiten und von Dampf- und Gasströmungen mittels des induktiven Strömungsmeßverfahrens möglich, wenn das strömende Medium durch Ionisation eine gewisse Leitfähigkeit annimmt. Zum Beispiel ist es möglich, ein Gas oder einen Dampf oder eine nicht leitende Flüssigkeit durch einen radioaktiven Stoff oder durch Bestrahlung mit kurzwelligen Strahlen zu ionisieren und dadurch leitend zu machen. Ein anderes Mittel besteht darin, Wechselspannungsentladungen durch die zu messende Flüssigkeit zu schicken, wozu man zur Vereinfachung des Aufwandes die Meßelektroden während der Messung selbst heranziehen kann. Nachdem die Flüssigkeit, der Dampf oder das Gas auf diese Weise leitend gemacht worden sind. kann die Messung in der an sich bekannten Art und Weise ausgefiihrt werden. The measurement of non-conductive liquids is also in accordance with the invention and of steam and gas flows using the inductive flow measurement method, when the flowing medium assumes a certain conductivity through ionization. To the For example, it is possible to use a gas or a vapor or a non-conductive liquid by a radioactive substance or by exposure to short-wave radiation to ionize and thereby make it conductive. Another means is to use AC voltage discharges by to send the liquid to be measured, for the sake of simplicity the effort can use the measuring electrodes during the measurement itself. After this the liquid, the vapor or the gas have been made conductive in this way. the measurement can be carried out in the manner known per se.
