Description

Differenzdruckmesser mit einer an einer Feder hängenden (Keßglocke Die Erfindung betrifft die bekannten, bei Strömungsmessern mit einer Drosselstelle verwendeten Differenzdruckmesser mit an einer Feder hängender Meßglocke. Sie besteht in der im Anspruch gekennzeichneten und im folgenden an Hand der Zeichnung näher erläuterten Anordnung der Feder, durch die insbesondere eine gedrungene Bauart der Meßvorrichtung erreicht wird.Differential pressure meter with a (Keßglocke The invention relates to the known flow meters with a throttle point used differential pressure meter with measuring bell hanging on a spring. she consists in the characterized in the claim and in the following with reference to the drawing in more detail explained arrangement of the spring, through which in particular a compact design of the Measuring device is achieved.

Die Meßfeder, die mit e bezeichnet ist, ist im Innern der Glocke a selbst angeordnet. Die Glocke a hat einen Schaft b, der mit seinem oberen Ende bei c mit der Glocke a verschraubt ist und dessen unteres Ende die Federmutter d trägt. An d ist die Feder e befestigt, deren anderes Ende auf der Federmutter f sitzt, die ihrerseits durch den innerhalb der Glocke a liegenden Rand des zylindrischen Quecksilberraumes (nicht dargestellt) oder, wie in der Abbildung gezeigt, durch ein besonderes .vorgesehenes Einsatzgefäß g gestützt wird, in welchem sich die Absperrflüssigkeit h befindet. Bei i und k wird der Schaft b und damit die Glocke geführt. Das Ganze ist dann in einem Druckgefäß L untergebracht, welches in bekannter Weise die beiden Anschlußstutzen na und n besitzt. Um die Feder e vor Rost zu schützen, ist der unter der Glocke befindliche Raum o mit 01 oder einer anderen schützenden Flüssigkeit gefüllt.The measuring spring, which is denoted by e, is arranged inside the bell a itself. The bell a has a shaft b which is screwed with its upper end at c to the bell a and whose lower end carries the spring nut d. The spring e is attached to d , the other end of which sits on the spring nut f, which in turn is supported by the edge of the cylindrical mercury chamber (not shown) inside the bell a or, as shown in the figure, by a special is, in which the shut-off liquid is h . At i and k , the shaft b and thus the bell are guided. The whole is then housed in a pressure vessel L, which has the two connecting pieces na and n in a known manner. To protect the spring e from rust, the space o under the bell is filled with 01 or another protective liquid.
