Abstract

Die Erfindung betrifft eine Vorrichtung mit einem Flüssigkeitsbehälter (16) mit ein oder mehreren Pumpen (14), einer Steuereinrichtung (18), welche eine oder mehrere Pumpen (14) in Abhängigkeit von der Höhe des Flüssigkeitsstandes in dem Behälter (16) ein- oder ausschaltet, und ein oder mehreren mit der Steuereinrichtung (18) verbundenen Sensoren (21, 22, 23, 24, 25) zur Erfassung ein oder mehrerer Flüssigkeitsniveaus, insbesondere Einschalt- und Ausschaltniveaus der Pumpen (14), und ein Verfahren zum Betrieb solcher Vorrichtungen oder damit ausgestatteter Anlagen. Die Vorrichtung passt während eines Betriebs das Ausschaltniveau mindestens einer der Pumpen (14) an (Fig. 4).

Figure imgaf001
The invention relates to a device with a liquid container (16) with one or more pumps (14), a control device (18) which one or more pumps (14) in dependence on the height of the liquid level in the container (16) on or and one or more sensors (21, 22, 23, 24, 25) connected to the control device (18) for detecting one or more fluid levels, in particular turn-on and turn-off levels of the pumps (14), and a method of operating such devices or equipment equipped with it. The device adjusts the shutdown level of at least one of the pumps (14) during operation (FIG. 4).
