Method for filling a target volume into a container, measuring arrangement and flowmeter

A measuring arrangement for filling a target volume into a container, comprising:

• at least one flowmeter for measuring the flow of a medium flowing into the at least one container;
• at least one actuator;
• at least one control unit;
• wherein the flowmeter has a computing unit;
• and
• wherein the filling process can be started and ended by activating the actuator;
• wherein the control unit is connected to the actuator and the flowmeter via a communication system, and the control unit is set up in such a way that, during operation, it sends a control command to the actuator to terminate the filling process when a defined limit value of the fill volume, which correlates with the target volume, is reached;
• and
• wherein the control unit and the computing unit of the flowmeter are designed and set up for carrying out a method including the steps of:
• starting the filling process;
• calculating the current fill volume by integrating the measured flow measurement values by the computing unit of the flowmeter;
• sending a fill message at defined time intervals with the current fill volume from the flowmeter to the control unit;
• predicting the remaining time until the fill volume limit is reached by the computing unit of the flowmeter;
• checking by the computing unit of the flowmeter whether the limit value of the fill volume is reached in time before the next fill message of the flowmeter is sent;
• if the limit value of the fill volume is reached in time before the next fill message of the flowmeter is sent, sending an additional message with the limit value of the fill volume at a predicted time in time before the next fill message to the control unit;
• and
• ending the filling process by a control command from the control unit.
