Description

Die in dem Patent 245150 beschriebene Einrichtung zur Messung von Schiffs- und Strömungsgeschwindigkeiten besteht aus einem von dem strömenden Mittel zu durchströmenden Kanal mit einer elektrischen Heizvorrichtung, die an einer Stelle des Kanals das durchströmende Mittel erhitzt, und einer Anordnung von Thermoelementen,. die den Temperaturunterschied des durchströmenden Mittels vor und hinter der erhitzten Stelle messen. \?orliegende Erfindung betrifft eine einfachere und sicherere Anordnung. Die Teile des Kanals, die nach der erhitzten Stelle hin und von ihr weg führen, sind parallel zueinander angeordnet, und es ist unmittelbar auf ihnen oder in ihnen eine einheitliche Thermöbatterie angebracht, die in Abhängigkeit von der in den beiden Rohren herrschenden Temperaturdifferenz Strom erzeugt, der zum Messen dient. Der geheizte Teil des Kanals liegt in dem Verbindungsstück der beiden parallelen Kanalteile. Dieser Teil des Kanals kann vorteilhaft aus einer ■ Mehrzahl feinerer U-förmiger Rohre bestehen, durch die in dünnen Fäden das strömende Mittel hindurchtritt. Bei dieser Anordnung" wird das strömende Mittel sehr, rasch und sehr gleichmäßig erhitzt wegen der gleichmäßigen Unterteilung, die es in den Rohren erfährt, und wegen der großen Oberfläche der Rohre, durch die ihm die Wärme zugeführt . wird.The device described in the patent 245150 for measuring ship and current velocities consists of a channel through which the flowing medium flows, with an electrical heating device which heats the flowing medium at one point of the channel, and an arrangement of thermocouples. which measure the temperature difference of the medium flowing through in front of and behind the heated point. \ ? The present invention relates to a simpler and safer arrangement. The parts of the duct that lead to and from the heated point are arranged parallel to one another, and a uniform thermal battery is attached directly to them or in them, which generates electricity depending on the temperature difference in the two pipes, which is used for measuring. The heated part of the duct lies in the connecting piece of the two parallel duct parts. This part of the channel can advantageously consist of a plurality of finer U-shaped tubes through which the flowing medium passes in thin threads. With this arrangement "the flowing medium is heated very, rapidly and very evenly because of the even division it experiences in the tubes and because of the large surface area of the tubes through which the heat is supplied.

Am besten ist es, zwei Systeme solcher U-förmiger Rohre zu verwenden, die zwischen sich den elektrischen Heizkörper einschließen. ' s It is best to use two systems of such U-shaped pipes, enclosing the electric radiator between them. ' s

In beiliegender Zeichnung ist eine Anordnung dieser Art schematisch dargestellt, und zwar in Fig. ι und 2 in zwei Ansichten, in Fig. 3 in einem Schnitt durch die Zu- und Abführungskanäle. Darin bedeutet α den Zuführungskanal, b den Abführungskanal, C1- und c2 die beiden . Systeme U-förmig gebogener Rohre, die zwischen sich den Heizkörper d einschließen, e sind die Thermoelemente, die an den Kanten der Kanäle a und b (bei f und g) ihre Lötstellen haben.In the accompanying drawing, an arrangement of this type is shown schematically, namely in Fig. 1 and 2 in two views, in Fig. 3 in a section through the supply and discharge channels. Here, α denotes the supply channel, b the discharge channel, C 1 - and c 2 the two. Systems of U-shaped bent tubes that enclose the radiator d between them, e are the thermocouples that have their soldering points on the edges of the channels a and b (at f and g).
