Abstract

Die Erfindung betrifft ein Verfahren und eine Steuereinrichtung zur Massedurchflußerfassung von kyrogenen Medien, insbesondere Flüssiggas wie tiefkaltem verflüssigtem Stickstoff, beim Abfüllen aus einem ortsfesten Vorratsbehälter (1) wie einem Kaltvergaser oder Kältetank, bei dem die aus dem Vorratsbehälter durch eine Abfüllleitung (2) abgefüllte Flüssiggasmenge durch eine Differenzdruck- oder Coriolis-Massedurchflußmessung erfaßt wird.
Erfindungsgemäß ist dadurch, daß beim Abfüllen des Flüssiggases aus dem Vorratsbehälter (1) in den Behälter (9) jede Flüssiggasmenge über eine Erfassung der Öffnungszeiten eines in der Abfüllleitung (2) angeordneten Magnetventils (3) gemessen und die Daten des Abfüllvorganges elektronisch ausgewertet werden, eine kostengünstige, robuste und flexible anwendbare Massedurchflußerfassung von kyrogenen Medien wie Flüssiggas beim Abfüllen aus ortsfesten Vorratsbehältern mit gleichzeitiger Erfassung und Auswertung aller relevanten Daten des Abfüllprozesses bei gleichzeitiger Prüfung der Anwender-Zugangsberechtigung und der Behälter-Zulassung gegeben.

The invention relates to a method and a control device for mass flow detection of kyrogenen media, in particular liquefied petroleum gas such as cryogenic liquefied nitrogen, during filling from a stationary reservoir (1) such as a cold gasifier or cold tank, in which the from the reservoir through a filling line (2) filled liquid gas is detected by a differential pressure or Coriolis mass flow measurement.
According to the invention characterized in that during filling of the liquefied gas from the reservoir (1) in the container (9) each amount of liquid measured by detecting the opening times of the filling line (2) arranged solenoid valve (3) and the data of the filling process are evaluated electronically, a cost-effective, robust and flexible applicable mass flow detection of kyrogenen media such as LPG when filling from stationary storage containers with simultaneous detection and evaluation of all relevant data of the filling process given while checking the user's access authorization and the container approval.
