Stand der TechnikState of the art
Zur Messung des Flüssigkeitsstands kann ein Schwimmer-, Flüssigkeitsdruck- oder Resonanz-Flüssigkeitsstandmeßgerät verwendet werden, die einen komplizierten Aufbau aufweisen, so dass die Herstellungskosten hoch sind.to Measurement of the liquid level can a float, fluid pressure or resonant liquid level gauge used be that have a complicated structure, so that the production costs are high.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Flüssigkeitsstand-Meßmodul zu schaffen, das durch den Unterschied der Flüssigkeitstemperatur und der Raumtemperatur den Flüssigkeitsstand messen kann.Of the Invention is based on the object, a liquid level measuring module create, by the difference of the liquid temperature and the Room temperature the liquid level can measure.
Der Erfindung liegt eine weitere Aufgabe zugrunde, ein Flüssigkeitsversorgungssystem zu schaffen, das das obengenannte Flüssigkeitsstand-Meßmodul enthält.Of the Another object of the invention is a liquid supply system to provide, which contains the above-mentioned liquid level measuring module.
Das Flüssigkeitsstand-Meßmodul kann den Stand einer Flüssigkeit in einem Behälter messen, wobei die Temperatur der Flüssigkeit anders ist als der Raumtemperatur, umfassend ein erstes Sensorelement, ein zweites Sensorelement und eine Meßeinheit, wobei das erste und zweite Sensorelement in einer ersten und zweiten Position des Behälters angeordnet sind und entsprechend der Temperaturänderung ein erstes und zweites Signal erzeugen können; und die Meßeinheit einen Controller enthält, der entsprechend den Sensorelementen mehrere Eingänge und mindestens einen Ausgang aufweist, wobei die Eingänge mit dem ersten und zweiten Sensorelement verbunden sind, wodurch das erste und zweite Signal an den Controller gesendet werden, der das erste und zweite Signal miteinander vergleicht und ein entsprechendes Steuersignal durch den Ausgang ausgibt.The Liquid level measuring module can the level of a liquid in a container measure, where the temperature of the liquid is different than the Room temperature, comprising a first sensor element, a second Sensor element and a measuring unit, wherein the first and second sensor elements in a first and second Position of the container are arranged and according to the temperature change, a first and second Can generate signal; and the measuring unit contains a controller, the according to the sensor elements more inputs and has at least one output, the inputs with the first and second sensor element are connected, whereby the first and second signal are sent to the controller, which is the comparing first and second signal with each other and a corresponding one Control signal outputs through the output.
Das Flüssigkeitsversorgungssystem besteht aus dem obengenannten Flüssigkeitsstand-Meßmodul und einer Flüssigkeitspumpe, die von dem Steuersignal des Flüssigkeitsstand-Meßmoduls gesteuert wird und Flüssigkeit in den Behälter pumpen kann.The Liquid supply system consists of the above-mentioned liquid level measuring module and a liquid pump, that of the control signal of the liquid level measuring module is controlled and liquid in the container can pump.
