Description

Anzeigevorrichtung- für Strömungsmesser Gegenstand der Erfindung ist eine Anzeigevorrichtung für Strömungsmesser mit Drosselstelle und Differenzdruckmesser, bei der an dem einen Ende eines doppelarmigen Hebels das Stellorgan samt Anzeigeorgan angebracht ist und an dem anderen Ende ein Kolben einer Dämpfungsvorrichtang als Gegengewicht bzw. Ausgleichgewicht hängt.Display device for flow meters is the subject of the invention a display device for flow meters with a throttle and differential pressure meter, at the one end of a double-armed lever the actuator including the indicator is attached and at the other end a piston of a damping device as Counterweight or balance weight is hanging.

Die Strömungsmesser bekannter Art haben den Nachteil, daß sie entweder zu empfindlich sind, die dann bei stoßweise wirkenden Strömungen unbrauchbare Ergebnisse zeigen, oder sie sind zu unempfindlich und geben die durch die Leitung strömende Menge nicht genau genug an. Diese Nachteile sollen durch die nachstehend beschriebene Bauart behoben werden.The flow meters of the known type have the disadvantage that they either are too sensitive, which would result in useless results in intermittent currents show, or they are too insensitive and give the flowing through the line Amount not accurate enough. These disadvantages are addressed by the one described below Design to be fixed.

Durch die Zeichnung ist eine Ausführungsart eines solchen Strömungsmessers schematisch dargestellt, die näher beschrieben werden soll.The drawing shows one embodiment of such a flow meter shown schematically, which will be described in more detail.

Der Messer besteht aus einem zusammengesetzten Hebelwerk, ähnlich wie bei einer zusammengesetzten Waage, wobei die inneren Glieder durch die äußeren wie durch die Gewicht- und Lastschale unter Spannung gehalten werden, so daß nur zwangsläufige Bewegungen stattfinden können. Die Lastseite ist hier beispielsweise die Schwimmerseite und durch eine Dämpfervorrichtung c, cl ersetzt, deren Kolben gleichzeitig als Ausgleichgewicht dient, während für die Gewichtsseite die Stangeh der Anzeigevorrichtung als Gegengewicht verwendet wird. Schwimmer a, Hebel b und Kurvenhebel d einerseits werden durch die Kolben der Dämpfervorrichtung c, cl, der Kurvenhebel k und Segmenthebel g andererseits durch die Stange der Anzeigevorrichtung ausgeglichen. Die Verbindung beider Aggregate wird beispielsweise durch ein Band f hergestellt, das durch die Schwere des Kolbens c und der Stange h in Spannung gehalten wird.The knife consists of a composite lever mechanism, similar like a compound balance, with the inner limbs through the outer how to be kept under tension by the weight and load cup, so that only inevitable movements can take place. The load side is here for example the float side and replaced by a damper device c, cl, the piston at the same time serves as a balance weight, while the bar is for the weight side the display device is used as a counterweight. Float a, lever b and Cam levers d on the one hand are by the piston of the damper device c, cl, the Cam lever k and segment lever g on the other hand by the rod of the display device balanced. The connection between the two units is made, for example, by a tape f made by the gravity of the piston c and the rod h in tension is held.

Der Kolben c wird in dem Zylinder cl geführt. Bei Verwendung von Luft oder Flüssigkeit kann die Bewegung des Kolbens c dem Gang des Strömungsgutes, ob gleichmäßig oder pulsierend, entsprechend eingestellt werden, so daß die Anzeigevorrichtung 'mit der größt zu erreichenden Genauigkeit in jedem Falle arbeitet. Der Kolben c dient mithin nicht allein zum Ausgleichen des Hebelsystems, sondern auch zur Dämpfung der durch die pulsierende Strömungsmenge auftretenden Stöße. Der Kolben c bewegt sich in dem Zylinder cl so gut wie reibungsfrei, so daß der Messer bei richtig gewählter Schwerpunktslage der Hebel sehr empfindlich ist, d. h. er wird bei der geringsten Veränderung des durch die Strömungsmenge erzeugten Druckunterschiedes in Bewegung tre= ten. Treten hingegen Stöße auf, wie dies durch die pulsierende Mengenentnahme der Fall ist, dann werden diese Stöße gedämpft, weil der Kolben sich nur der Luft- bzw. Flüssigkeitsverdrängung entsprechend bewegen kann. Die Empfindlichkeit des Messers wird dadurch nicht beeinflußt.The piston c is guided in the cylinder cl. When using air or liquid, the movement of the piston c the course of the flow material, whether uniformly or pulsatingly, can be set accordingly, so that the display device 'works with the greatest possible accuracy in each case. The piston c is therefore not only used to balance the lever system, but also for damping the shocks caused by the pulsating flow rate. The piston c moves in the cylinder cl as good as frictionless, so that the knife when correctly selected The center of gravity of the levers is very sensitive, d. H. he will at the slightest Change in the pressure difference generated by the flow rate in motion occur. On the other hand, shocks occur, as is the case with the pulsating amount of water being withdrawn is the case, then these shocks are dampened because the piston is only or fluid displacement can move accordingly. The sensitivity of the This does not affect the knife.
